glsl: Correctly handle unary plus operator.

Browse source 
Previously, any occurence of the unary plus operator would trigger a
bogus type mismatch error. Fix this by making the ast_plus case look
more like the ast_neg case as far as type-checking is concerned.

With this change the shaders/CorrectPreprocess8.frag test in piglit
now passes.
