Rewrite terrible upstream .service files:

* added meta "gitlab.service" that work alike corresponding init.d script
 * new .service files with support for "reload" and propagation of "reload" from "gitlab.service"
 * non-forking PIDFILE-less implementation

This commit fixes services' start-up and postinst error on first install.
