zink: don't create invalid inputs in zink_create_quads_emulation_gs

Browse source 
The helper was creating input locations for some builtin bariables.

This caused validation errors in zink because those builtins can't be
used as input.

Fixes: e2220ee55e ("zink: filled quad emulation gs generation function")
