lavc/av1*: fix exporting framerate

* take num_ticks_per_picture_minus_1 into account, since that is a part
  of the framerate computation
* stop exporting num_ticks_per_picture_minus_1 into
  AVCodecContext.ticks_per_frame, as that field is used for other
  purposes (in conjunction with repeat_pict, which is not used at all by
  av1)
