avformat/mov: avoid seeking back to 0 on HEVC open GOP files
ab77b878f1 attempted to fix the issue of broken packets being sent to
the decoder by implementing logic that kept attempting to PTS-step
backwards until it reached a valid point, however applying this
heuristic meant that in files that had no valid points (such as HEVC
videos shot on iPhones), we'd seek back to sample 0 on every seek
attempt. This meant that files that were previously seekable, albeit
with some skipped frames, were not seekable at all now.
Relax this heuristic a bit by giving up on seeking to a valid point if
we've tried a different sample and we still don't have a valid point to
seek to. This may some frames to be skipped on seeking but it's better
than not being able to seek at all in such files.
