Noticed on my quest to make Lix buildable against multiple nixpkgs' to
provide pre-warmed caches for the flake on AFNix's Hydra.
`pkgs.systemd` has a new patch policy[1] that only allows patches for
hotfixes and fundamental incompatibilities. As such, the patch that
allows nspawn workloads to start without a `/usr/bin` was removed with the
recommendation to create that stub yourself.
