If the only stage is MESA_SHADER_COMPUTE, we should complain that
there's nothing coming out of the geometry shader stage just as
we would if the first stage were MESA_SHADER_FRAGMENT.
Also, it's valid for tessellation shaders to be the stage producing
transform feedback varyings, so mention those in the compiler error.
Found by inspection.
