lavfi/video: set output frame w/h properties in default_start_frame()

Browse Source 
Use the same values of the video output link.

Avoid the need to override the default_start_frame() with an ad-hoc
start_frame() callback.

In particular, fix the super2xsai filter which was setting the
input w/h values in the output.
