lavf/mux: do not pass a copy of the packet to write_packet().

Browse Source 
Sometimes the muxer modifies the packet, like for instance lavf/mp3enc
changing pkt->destruct in order to keep a copy. These changes must be
kept, even though the muxer behaviour is questionable. Regression since
0072116.

Fixes #2124.
