glsl: Match order of gl_LightSourceParameters elements.

spotExponent and spotCosCutoff were swapped in the
gl_builtin_uniform_element struct.
Now the order matches across gl_builtin_uniform_element,
glsl_struct_field and the spec.

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.
