    data: Add a way for Rygel to be started via user systemd
    
    This will allow better tracking of whether rygel is running, ensuring
    that even if the manager to enable/disable its startup
    (gnome-settings-daemon) crashes and needs to restart, its status is
    still available by querying the user systemd.
