fftools/ffmpeg_enc: always use video frame durations when available

Previously they would only be used with trivial filtergraphs, because
filters did not handle frame durations. That is no longer true - most
filters process frame durations properly (there may still be some that
don't - this change will help finding and fixing them).

Improves output video frame durations in a number of FATE tests.
