ghe-rsync-backup doesn't compress git object/pack data

This should be a nice little optimization. The auxiliary files,
packed-refs, refs, and reflogs will benefit from compression but
compressing the git object and pack data is just wasting CPU since
it's already compressed and quite a bit better than what you get
from just zlib.
