The gerrit trigger will extract the correct meta-* branch but need to
be sure to extract the matching openbmc/openbmc branch.

Once openbmc-test-automation branches, support for that will be added
to this script.

Testing:
Put up dummy commit in thud branch and verified it extracted appropriate
branch and built ok.
