Revert "avformat: don't mark buffer as need to be writable, as we don't write into it directly"

This reverts commit 75890fb5.

This caused infinite loops in aviobuf when muxing to mkv.
write_flag seems to mean "mux" versus "demux".
The real meaning might be lost on us for lack of a libavformat documentation translator.
