demux_lavf: Adding av_dup_packet() missing from recent 6e8d420a41 

Commit 6e8d420a41 ("demux: avoid a copy of demux packets with lavf,
reduce padding") was missing an av_dup_packet() line. As a result at
least formats that use parsing on the lavf side could fail (with
parsing the packet may contain pointers to temporary fields that
will be overwritten/freed when reading further packets, and
av_dup_packet() is required to allocate permanent storage).
