glsl: Fix gl_NormalScale.
GLSL shaders can access the normal scale factor with the built-in
gl_NormalScale. Mesa's modelspace lighting optimization uses a different
normal scale factor than defined in the spec. We have to take care not
to use this factor for gl_NormalScale.
Mesa already defines two seperate states: state.normalScale and
state.internal.normalScale. The first is used by the glsl compiler
while the later is used by the fixed function T&L pipeline. Previously
the only difference was some component swizzling. With this commit
state.normalScale always uses the normal scale factor for eyespace
lighting.
