deploy_production_local: Correctly accept prod branch as clean.

We were declaring the server cautotest as dirty because it has a local
'prod' branch. We've decided to keep this branch for now, so it should be
treated as clean.

Also redo some command output to make it more understandable, especially
when --dryrun is specified.

BUG=chromium:425636
TEST=Unittests + dryrun testing.
