Looking at places that GL_RGBA32UI is mentioned, it seems like we also
need a case for this extension in fbobject.c:_mesa_base_fbo_format().

Looks like teximage.c:get_sized_format_info() doesn't want it because
that list is supposed to just be table 3.21 of the GL 3.3 spec for
glTexBuffer() (so it explicitly doesn't include this format).
