fftools/ffmpeg: always generate CFR output when -r is used 

Current code may, depending on the muxer, decide to use VSYNC_VFR tagged
with the specified framerate, without actually performing framerate
conversion. This is clearly wrong and against the documentation, which
states unambiguously that -r should produce CFR output for video
encoding.

FATE test changes:
* nuv-rtjpeg: replace -r with '-enc_time_base -1', which keeps the
  original timebase. Output frames are now produced with proper
  durations.
* filter-mpdecimate: just drop the -r option, it is unnecessary
* filter-fps-r: remove, this test makes no sense and actually
  produces broken VFR output (with incorrect frame durations).
