v3d: only expose rgba buffer-textures

Browse source 
Unlike textures, we can't easily do format-conversion of the data
before, because the source is a buffer object and not a texture object.

But we already have a hammer for this in Mesa, which means we'll drop
the ARB_texture_buffer_object extension support, but only for the OpenGL
compatibility profile. We still get GL 3.2 exposed.
