fftools/ffmpeg_dec: move sub2video submission to ffmpeg_filter

Browse Source 
This code is a sub2video analogue of ifilter_send_frame(), so it
properly belongs to the filtering code.

Note that using sub2video with more than one target for a given input
subtitle stream is currently broken and this commit does not change
that. It will be addressed in following commits.
