f_lavfi: support setting common filter options like "threads"

Browse Source 
AVFilterContext instances support some additional AVOptions over the
actual filter. This includes useful options like "threads". We didn't
support setting those for the "direct" wrapper (--vf=yadif:threads=1
failed). Change this. It requires setting options on the AVFilterContext
directly, except the code for positional parameters still needs to
access the actual filter's AVOptions.
