drisw: move zink down the list below the sw drivers.
We don't ever want drisw path picking zink as the driver, we can revisit this when the penny wrapper work gets further along. This selection causes systems with nvidia/intel dual-gpus to try and pick the intel gpu for rendering in the nvidia context if there is no nvidia GL driver or accel doesn't work. This is a partial revert of the original commit. Fixes: 4a3b42a7 ("drisw: Prefer hardware-layered sw-winsys drivers over pure sw") Acked-by:Jesse Natalie <jenatali@microsoft.com> Reviewed-by:
