gallium: Set renderbuffer's InternalFormat when rendering to texture
When an FBO is rendering to a texture (rather than a renderbuffer),
Gallium sets up an internal renderbuffer to handle the rendering, and
copies over enough texture state to make this work.
InternalFormat was missed out, causing glTexCopyImage to take a slow
path unnecessarily.
