mesa: mark GL_RGB9_E5 as not color-renderable

Browse source 
The GL 4.4 spec says it's not color-renderable and not accepted
by RenderBufferStorage. The EXT_texture_shared_exponent spec says
it's not color-renderable but it's accepted by RenderBufferStorageEXT.
This seems to be a bug in the extension spec.

Let's do what GL 4.4 says.
