Test that glProgramParameter() triggers the required errors.
The geometry shader output primitive type is limited to a subset
of OpenGL primitive types.
>From the ARB_geometry_shader4 spec (section Errors):
"The error INVALID_VALUE is generated by ProgramParameteriARB if <pname> is
GEOMETRY_OUTPUT_TYPE_ARB and <value> is not one of POINTS, LINE_STRIP or
TRIANGLE_STRIP."
