The server has 96 cores and 128 GB of RAM, so run 20 builders on it.
This adds the Dockerfile each builder runs in, and the machinery to
run 20 copies of the Docker container.
Also reduce some logspam in the buildlet's shutdown.
(The dashboard/builders.go entry for this builder was added previously
in https://golang.org/cl/39851)

Previously it wasn't noticing their death until the next health check.
Take advantage of that the revdial is always blocked in a Read, so it
will see a TCP shutdown in the case of normal shutdowns. (health checks
will still catch disappearing machines)

If the server's conn stopped reading, we acquired a Lock twice
(blocking forever) and never killing all the active connections on it.
Add test.

* reverse buildlet rework (multiplexed TCP connections, instead
of a hacky reverse roundtripper)
* scaleway ARM image improvements
