Add a bunch of debugging prints to the Mac OS watcher.

This reverts r30184, which in turn reverted r30181. It correctly detects whether
it's running on a buildbot in a way that will work for the vm-mac-release bot.

This is a temporary CL intended to help provide information about a test failure
that's only reproducing on the build bot. It will be rolled back as soon as
sufficient information is gathered.

A file watcher. It monitors (currently by polling) for changes to contents of directories and notifies you when files have been added, removed, or modified.
