Anton Khirnov daca5d1241 fftools/ffmpeg_filter: refactor setting input timebase

Treat it analogously to stream parameters like format/dimensions/etc.
This is functionally different from previous code in 2 ways:
* for non-CFR video, the frame timebase (set by the decoder) is used
  rather than the demuxer timebase
* for sub2video, AV_TIME_BASE_Q is used, which is hardcoded by the
  subtitle decoding API

These changes should avoid unnecessary and potentially lossy timestamp
conversions from decoder timebase into the demuxer one.

Changes the timebases used in sub2video tests.
