avformat/mov: discard data streams with all zero sample_delta
Streams with all zero sample_delta in 'stts' have all zero dts.
They have higher chance be chose by mov_find_next_sample(), which
leads to seek again and again.
For example, GoPro created a 'GoPro SOS' stream:
Stream #0:4[0x5](eng): Data: none (fdsc / 0x63736466), 13 kb/s (default)
Metadata:
creation_time : 2022-06-21T08:49:19.000000Z
handler_name : GoPro SOS
With 'ffprobe -show_frames http://example.com/gopro.mp4', ffprobe
blocks until all samples in 'GoPro SOS' stream are consumed first.
