James Almer 2e503a9b94 fftools/ffmpeg_demux: don't flag timestamps as unreliable if they are generated 
Regardless of the source being an AVFMT_NOTIMESTAMPS format, if the timestamps
are generated like when using the use_wallclock_as_timestamps demuxer option,
then they are reliable.

Fixes ticket #11268
