audio/filter: change filter callback signature

The new signature is actually closer to how it actually works, and
someone who is not familiar to the API and how it works might make fewer
fatal mistakes with the new signature than the old one. Pretty weird.

Do this to sneak in a flags parameter, which will later be used to flush
remaining data of at least vf_lavfi.
