build: new vaapi hwaccel API does not use av_image_copy_uc_from() 

Not even Libav does. Whoops. The developer who wrote the FFmpeg code for
this said he could not find any improvements when using the "GPU memcpy"
; instead, it made it actually slower on some hardware.

It's not clear to what extent the "GPU memcpy" was needed for vaapi, but
hopefully not very much (see #2317).

This commit enables use of the new vaapi API by default with FFmpeg.
