avfilter/vf_fps: properly preserve CEA-708 captions
The existing implementation made an attempt to remove duplicate
captions if increasing the framerate, but made no attempt to
handle reducing the framerate, nor did it rewrite the caption
payloads to have the appropriate cc_count (e.g. the cc_count needs
to change from 20 to 10 when going from 1080i59 to 720p59 and
vice-versa).
Make use of the new ccfifo mechanism to ensure that caption data
is properly preserved.
