    dbusServices/screensaver: Disable auto-shutdown
    
    For the screensaver service, it is quite normal that a consumer only
    subscribes to the "ActiveChanged" signal without calling any methods.
    
    The result is that we don't know about the consumer, and shut down
    the service anyway after we hit the timeout.
    
    If this happens, we break functionality like gnome-settings-daemon's
    screen blanking on idle.
    
    Fix this by simply disabling auto-shutdown for the service, which
    also reflects the expectation that the screen saver service is
    always running in a GNOME session.
