vapostproc: Build classification dynamically.

Browse source 
By default, the classification is
"Converter/Filter/Colorspace/Scaler/Video/Hardware", but if VA
post-processor driver supports either color balance, skin tone
enhancement, sharpening or noise reduction, "Effect" is added.

Thus, if vapostproc ranking is raised, it can be chosen by
autovideosink.
