glsl: add builtins for geometry shaders.

v2 (Paul Berry <[email protected]>): Account for rework of
builtin_variables.cpp.  Use INTERP_QUALIFIER_FLAT for gl_PrimitiveID
so that it will obey provoking vertex conventions.  Convert to GLSL
1.50 style geometry shaders.

v3 (Paul Berry <[email protected]>): Be less obscure about
setting interpolation field of gl_Primitive variables.
