bug 1481612 - vendor an unpacked win64 wheel of psutil 5.4.3. r=gps 

This change uses the previously added `--with-windows-wheel` option to vendor
a win64 wheel of psutil. This patch was produced by running:
`mach vendor python --with-windows-wheel psutil==5.4.3`.

We vendor this wheel unpacked so that we can insert it into sys.path in mach
without needing a virtualenv in which to install a wheel with pip, since we
have a chicken-and-egg problem there where configure creates the virtualenv
but we'd like to be able to use psutil before we run configure.

Summary
=======
psutil (process and system utilities) is a cross-platform library for
retrieving information on **running processes** and **system utilization**
(CPU, memory, disks, network, sensors) in Python.
It is useful mainly for **system monitoring**, **profiling and limiting process
resources** and **management of running processes**.
It implements many functionalities offered by UNIX command line tools such as:
ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat,
iotop, uptime, pidof, tty, taskset, pmap.
psutil currently supports the following platforms:
- **Linux**
- **Windows**
- **OSX**,
- **FreeBSD, OpenBSD**, **NetBSD**
- **Sun Solaris**
- **AIX**
...both **32-bit** and **64-bit** architectures, with Python
versions from **2.6 to 3.6**.
`PyPy <http://pypy.org/>`__ is also known to work.

Projects using psutil
=====================
At the time of writing psutil has roughly
`2.9 milion downloads <https://github.com/giampaolo/psutil/issues/1053#issuecomment-340166262>`__
per month and there are over
`6000 open source projects <https://libraries.io/pypi/psutil/dependent_repositories?page=1>`__
on github which depend from psutil.
Here's some I find particularly interesting:

Summary
=======
psutil (process and system utilities) is a cross-platform library for
retrieving information on **running processes** and **system utilization**
(CPU, memory, disks, network, sensors) in Python.
It is useful mainly for **system monitoring**, **profiling and limiting process
resources** and **management of running processes**.
It implements many functionalities offered by UNIX command line tools such as:
ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat,
iotop, uptime, pidof, tty, taskset, pmap.
psutil currently supports the following platforms:
- **Linux**
- **Windows**
- **OSX**,
- **FreeBSD, OpenBSD**, **NetBSD**
- **Sun Solaris**
- **AIX**
...both **32-bit** and **64-bit** architectures, with Python
versions from **2.6 to 3.6**.
`PyPy <http://pypy.org/>`__ is also known to work.

Notes about unicode handling in psutil
======================================
In psutil these are the APIs returning or dealing with a string
('not tested' means they are not tested to deal with non-ASCII strings):
* Process.cmdline()
* Process.connections('unix')
* Process.cwd()
* Process.environ()
* Process.exe()
* Process.memory_maps()
* Process.name()
* Process.open_files()
* Process.username() (not tested)
* disk_io_counters() (not tested)
* disk_partitions() (not tested)
* disk_usage(str)
* net_connections('unix')
* net_if_addrs() (not tested)
* net_if_stats() (not tested)
* net_io_counters() (not tested)
* sensors_fans() (not tested)
* sensors_temperatures() (not tested)
* users() (not tested)
* WindowsService.binpath() (not tested)
* WindowsService.description() (not tested)
* WindowsService.display_name() (not tested)
* WindowsService.name() (not tested)
* WindowsService.status() (not tested)
* WindowsService.username() (not tested)
In here we create a unicode path with a funky non-ASCII name and (where
possible) make psutil return it back (e.g. on name(), exe(), open_files(),
etc.) and make sure that:
* psutil never crashes with UnicodeDecodeError
* the returned path matches
For a detailed explanation of how psutil handles unicode see:
- https://github.com/giampaolo/psutil/issues/1040
- http://psutil.readthedocs.io/#unicode
