* 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

Currently 'run_task' tasks have no easy way to depend on a build task. For example, some
python unittests need a Firefox binary for their tests, like the mozrunner tests and future
test harness selftests (like mochitest tests).
This patch allows kinds to add a new key to the kind config which maps test platforms to
build-labels. Then 'run_task' jobs can add a 'requires-build': true field to get a build
dependency automatically added. The build artifact url will also be stored in the
$GECKO_INSTALLER_URL environment variable on the test host.
