fix(systemd-hostnamed): add missing dbus-org.freedesktop.hostname1.service

Without this service, hostnamectl fails to run in the initrd.

```
sh-5.2# hostnamectl
Failed to query system properties: Could not activate remote peer: activation request failed: unknown unit.
sh-5.2# systemctl status dbus | grep hostname
Dec 22 11:07:56 sd-net-test dbus-broker-launch[216]: Activation request for 'org.freedesktop.hostname1' failed: The systemd unit 'dbus-org.freedesktop.hostname1.service' could not be found.
```
