Fix negative position for clipped media

Browse source 
With this CL:
- The large timestamp offset added by ExoPlayer so that decoders
don't see any negative timestamps is removed before passing the
timestamp to the AudioGraph.
- Clipped media timestamps are offset by the clipping start position
before being passed to the AudioGraph.
- The offset added to the audio buffer timestamps is removed when
computing the audio sink position, to convert them back to the
timestamps passed by the player.
