system: always add /run to /etc/synthetic.conf on macOS 10.15 onwards

Browse source 
Currently if nix-darwin is uninstalled then reinstalled without
rebooting, then the `/run` symlink will still remain and nix-darwin
won't readd `run` to `/etc/synthetic.conf` meaning the system will be
broken on next reboot.
