[FFmpeg-cvslog] avformat/nullenc: Use ff_interleave_packet_passthrough()

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Sat Oct  9 16:34:13 2021 +0200| [ce8f77a903e1108bde774d5e0e59d8cd24f18c46] | committer: Andreas Rheinhardt

avformat/nullenc: Use ff_interleave_packet_passthrough()

It avoids the overhead of the packet list; furthermore, using
ff_interleave_packet_per_dts() is wrong for the null muxer anyway,
because said muxer accepts packets without timestamps, which
ff_interleave_packet_per_dts() can't handle.
