handbrake: fix missing audio

We build HandBrake with a newer ffmpeg than upstream expects,
triggering a problem where the audio samplerate defaults to zero
because HandBrake was not explicitly setting it.

This has been fixed in HandBrake upstream, but we must cherry pick
this change in order to produce videos with audio until HandBrake
1.3.0 is released.
