playsink: send navigation event to the sink as a fallback

When the video sink is a fakesink, which does not implement the
navigation interface, playsink will drop the navigation command.
In this case, send to the video sink as a fallback. It breaks
the interface abstraction, but is better than just dropping the
navigation event.
