vaapi_encode: Pass framerate parameters to driver
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)
