glsl: Fix #pragma invariant(all) language version check.

It was using state->Const.GLSL_100ES, which is set if the driver
supports ARB_ES2_compatibility or we're in ES2 mode.  Instead, it should
use state->language_version, as that represents the actual GLSL version
of the shader being compiled.

Since the correct logic is < 120 && !100, just make it == 110.
