st/nine: Fix ff SPECULARENABLE

We were (wrongly) adding specular to diffuse
in vertex shaders when SPECULARENABLE was set.

However the spec says specular has to be added
after texture processing (which is in ps).
Besides SPECULARENABLE is flagged as a pixel state.

There was unused support for SPECULARENABLE
in the ps ff code.
Remove the vs code, and use the ps code.
