[PATCH] git-p4.py: Don't try to rebase on submit from bare repository

["Amadeusz Żołnowski" <aidecoe@aidecoe.name>]

git-p4 can be successfully used from bare repository (which acts as a
bridge between Perforce repository and pure Git repositories). On submit
git-p4 performs unconditional rebase. Do rebase only on non-bare
repositories.
