FFmpeg has removed this field and usage of it in chromium must be
removed before the ffmpeg dependency is updated. The chromium media
change can be found here:

The usage of the field in webrtc seems only to be for sanity checking,
so it should be just safe to remove entirely, since webrtc does not
expect re-ordering at all.
