Bug 1289249 - Use vendored tooltool.py in SpiderMonkey tasks; r=dustin

Previously, SpiderMonkey tasks were using tc-vcs to clone the tooltool
repository so they could have access to tooltool.py. tooltool.py is
already in the execution environment courtesy of being part of the
source checkout. So use it from there.

One less dependency on a 3rd party service at run-time. One less
point for a MITM attack against our automation.
