avcodec/mpeg4videodec: Keep data_partitioning in sync between threads

Fixes frame-threaded decoding of samples created by concatting
a video with data partitioning and a video not using it.
(Only the MPEG-4 decoder sets this, so it is synced in
mpeg4_update_thread_context() despite being a MpegEncContext-field.)
