Fix two problems that would cause HB to hang in the muxer whenever the input content's video finished before audio:

 - sync has to keep processing until all its input fifos report eof otherwise it won't send an eof on all its output fifos.
 - do_job has to wait for muxer to finish. Waiting for anything earlier in the pipeline (we were waiting for the video encoder) can cause other parts of the pipeline to get terminated early which will result in lost data & no eofs.
