[yocto-autobuilder-helper][PATCH] janitor/ab-janitor: attempt initial clones until success

[Michael Halstead]

If the git clone operations don't succeed the mirror_processor thread
will spin updating nothing and index builds will fail. Instead the
thread will attempt the clones as many times as needed logging each
failure.

These are bare mirrors so look for the refs dir instead of .git.
