Docker-worker's `command` field is actually not required, as it will run a
docker image's default command when command is not specified.

* add run.using = 'run-task' for native-engine
* modify run-task to run on OS X
- not as root
- without assuming /home/worker (using ~ and os.expanduser instead)
- hg is in /usr/local/bin on OS X; trust the PATH
* add_build_dependency isn't docker-worker specific, so just rename
* support_vcs_checkout modified to omit caches on native-engine
* don't download fingerprints on OS X; these hosts are configured with
the proper fingerprint via puppet

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.
