vo_opengl: do not use vaapi-over-GLX

Browse Source 
This backend is selected if vaapi is available, but vaapi-over-EGL is
not. This causes various issues around the forced RGB conversion, which
is done with fixed, usually incorrect parameters.

It seems the existing auto probing check is too weak, and doesn't really
prevent it from getting loaded. Fix this by adding a flag to not ever
load this during auto probing.

I'm still not deleting it, because it's useful for testing on nvidia
machines.

See #4555.
