avformat/fifo: Check for keyframe video type before stop dropping

The current behavior when using restart_with_keyframe is that it will
recover if it also encounters any audio packet, as they are flagged as a
keyframe.

The expectation is that packets are dropped until the next _video_
keyframe.

To fix that, check if exists a video stream, if it exists check the
packet stream codec type, only letting it recover when it is a video
one. If there is no video stream, resume to the original behavior, not
checking the codec type.

Fixes ticket: #11467
