Only join video graph output in playlist mode.

DefaultVideoSink.join() was called when join() was called on the
InputVideoSink. This makes sense in playlist mode but we shouldn't
join if the VideoGraph output is considered as a single clip.

This change is no-op. Indeed, for CompositionPlayer, the
allowedJoiningTimeMs is set to 0, so that join doesn't have any effect.
