Subject: update-rc.d.bbclass: make prerm and postrm dpkg-compatible

* prerm : only stop service at the "upgrade" and "remove" steps
* postrm : only remove symlinks at the "remove" and "purge" steps, after
  checking the init script no longer exists

Subject: gitver.bbclass: fix git dependency tracking

.git/HEAD doesn't usually change on a commit, but the ref it points to
(e.g. .git/refs/heads/master) should. Handle this and another couple of
cases: if a tag is added without a new commit, or if the ref is in
packed-refs.
