videotoolbox: require I-frame for h264

This fixes BadDataErr when playing streams in the middle (when video track is
disabled and enabled).

This happened a lot when running chromecast in the middle of playback.

Furthermore, a BadDataErr from the decoder, while the videotoolbox encoder is
running cause random crashes.

(cherry picked from commit 60f8fff1d35b7bbd264a70bc6a6a930a344870a0)
