mesa: tweak mipmap level selection for cube maps

This is just a hack.  After we convert the 3D texcoord into a face plus 2D
texcoord we need to recompute the partial derivatives and mipmap LOD.
But we don't have the info to do that.  Adjusting the original mipmap
level by -1 seems to give somewhat better results than before though.
