Now that VP9 streams can't be wrongly muxed anymore after commit
0c162854c1, this change is not strictly necessary. And since there's no
real way to enforce or guarantee the presence of specific bsfs in
libavcodec as required by libavformat at runtime, maybe it's best to
leave it as an optional feature.
So patch dropped unless people speak in favor of this change.
