fftools/ffmpeg: Fix leak of AVFilterInOut in case of error

The AVFilterInOuts normally get freed in init_output_filter() when
the corresponding streams get created; yet if an error happens before
one reaches said point, they leak. Therefore this commit makes
ffmpeg_cleanup free them, too.

Fixes ticket #8267.
