nixos/gnome3: launch gnome-shell wayland with RT scheduling
We create a wrapper which launches gnome-shell with the correct environment and cap_sys_nice. We can then override gnome-shell-wayland.service to use this wrapper. NOTE: We need to force clear the environment, because the defaults aren't good for user services. That should probably be fixed.
