git-remote-testgit: only push for non-local repositories

Trying to push for local repositories will fail since there is no
local checkout in .git/info/... to push from as that is only used for
non-local repositories (local repositories are pushed to directly).

This went unnoticed because the transport helper infrastructure does
not check the return value of the helper.
