glsl: Apply the link error conditions to GL_ARB_fragment_coord_conventions

Link error conditions added in previous patch are equally applicable
to GL_ARB_fragment_coord_conventions implementation. Extension's spec
says:
   "If gl_FragCoord is redeclared in any fragment shader in a program,
    it must be redeclared in all the fragment shaders in that program
    that have a static use of gl_FragCoord. All redeclarations of
    gl_FragCoord in all fragment shaders in a single program must have
    the same set of qualifiers."
