fftools/ffmpeg: supply hw device context to probe-filtergraphs

Browse Source 
I.e. those that are only used to figure out input/output counts, since
some filters might expect a valid hw device in init and refuse to
initalize otherwise.

This requires complex filtergraphs to be created in a separate step
after parsing global options, after all hw devices are guaranteed to
exist.
