glsl: added uniform initializer check

GLSL 1.10 disallows initializers for uniforms but GLSL 1.20 and later
allows them.  This patch uses the #version directive to allow/disallow
uniform initializers.

This addresses bug 25807, but piglit also needs to be fixed to specify
the GLSL version in the shader.
