initrd: add unit files needed for basic systemd-in-initrd support
This will:
* mount all configured filesystems (typically the rootfs on /sysroot)
* reload the configuration to pick up anything from the mounted fs (typically

* mount any newly configured filesystems (typically /usr on /sysroot/usr, if
