    data: Add a way for gnome-user-share to be started via user systemd
    
    This will allow better tracking of whether gnome-user-share-webdav 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.
