Search Google Storage for trybot image artifacts.

Sometimes trybot jobs fail in the testing phase, but the build
finished and a build artifact exists.  To deal with this, instead
of checking the trybot job status, we just search for the build
artifact in google storage.  This also removes the
'--chrome_rev=tot' flag from the buildbot command.
