vaapi_encode: Pass framerate parameters to driver

Browse Source 
Only do this when building for a recent VAAPI version - initial
driver implementations were confused about the interpretation of the
framerate field, but hopefully this will be consistent everywhere
once 0.40.0 is released.

(cherry picked from commit ff35aa8ca4069bf1543adeec4c28e51e4a012eee)
