Fix typo, use rancher/permissions

[HarrisonWAffel]

Proposed Changes

Fixes a typo in config.go and removes the windows specific ACL logic in favor of the rancher/permissions library. The logic in acl/acl_windows.go was taken directly from rancher/permissions, so there is no functional difference, this is simply addressing tech debt.
