a set ost->frame_rate does not imply CFR in ffmpeg

The changed fate tests had all wrong packet durations
(like 1/1000 or 1/90000)

There might be more cases in which is_cfr could be set

Chapter-indexing can be expensive since chapters may be interspersed
throughout the entire file and may require many seeks - especially
costly when consuming a video over a remote protocol like http.
Furthermore it is often unnecessary, especially when only trying to get
video info (e.g. via ffprobe).

IO context is flushed after each fragment. Also flush it after
writing the initial moov, to have it behave in the same way.
