ad_lavc: skip fully skipped frames 

Fixes stupid messages with a opus/mkv test file that had an absurdly
huge codec delay.

This file fully skips several frames at the start. ad_lavc.c trimmed
these frames to 0 samples and returned them. The next layer
(f_decoder_wrapper.c) saw discontinuous PTS values, because the PTS
values increased by a frame, but amounted to 0 audio samples. This was
harmless, but logged PTS discontinuity errors.
