fftools/ffmpeg_filter: stop accessing OutputStream.[max_]frame_rate 

Pass them to ofilter_bind_ost() via OutputFilterOptions, as is done for
most other data it needs. OutputStream.[max_]frame_rate/force_fps are no
longer used outside of ffmpeg_mux*, and so can be made private.

This is a step toward decoupling encoders from muxers.
