Similar to the VAAPI_X11 bits, guard all the VAAPI_DRM parts behind a
compiler guard.

No it isn't.
Originally there wasn't a possibility to link with any winsys here - libavcodec
users had to get the device themselves and pass it in.
The winsys link was added to the ffmpeg utility initially for command-line use
and then moved to libavutil when it was clear that it would be useful to other
library users; there isn't any requirement to use it, though. (E.g. disable it
and note that programs handling the winsys themselves like mpv and vlc still
work perfectly well.)
