fftools/ffmpeg_filter: only use fallback parameters when necessary

Browse Source 
With complex filtergraphs it can happen that the filtergraph is
unconfigured because some other filter than the one we just got EOF on
is missing parameters.

Make sure that the fallback parametes for a given input are only used
when that input is unconfigured.
