We want to get rid of specialFileSystems / earlyMountScript eventually and
there is no need to run this before systemd anymore now that
the wrappers themselves are set up in a systemd unit since https://github.com/NixOS/nixpkgs/pull/263203
Also this is needed to make soft-reboot work. We want to make sure
that we remount /run/wrappers with the nosuid bit removed on soft-reboot
but because @earlyMountScript@ happens in initrd, this wouldn't happen
