It is unnecessary because an av_shrink_packet() a few lines below
will set the size; furthermore, it is actually harmful, because
av_shrink_packet() does nothing in case the size already matches,
so that the packet's padding is not correctly zeroed.

I was about to make append_packet_chunked non-static, but then I noticed
that it unrefs the packet if the end size is zero (this might cause
problems for side-data only packets).
