Anton Khirnov 5e1a3ea3ba lavc: move the vaapi encoders further down in the list of codecs 
Right now they are the first encoders for those codecs in the list, so
they are selected when the caller requests a codec by id.
Since they require special treatment, they should not be selected by
default if there are other encoders (e.g. libx264/5) available.
