glsl: add driconf to zero-init unintialized vars
Some games are sloppy.. perhaps because it is defined behavior for DX or perhaps because nv blob driver defaults things to zero. So add driconf param to force uninitialized variables to default to zero. This issue was observed with rust, from steam store. But has surfaced elsewhere in the past.
