Subject: make-rhat-patches: Use shallow clone


The selinux-policy repos are quite big - use --depth=1 to fetch only the
latest commit of the requested branch, to save network traffic and time.

A possible downside of this is that one can no longer pass a commit ID
via REPO_SELINUX_POLICY_*BRANCH, but that's unlikely to be useful in
practice.
