fix backport of 70b19acf
    
    The patch was missing an important hunk of the original diff which
    converted another `ln_r` to `systemctl set-default`. Without it, the
    initrd would try to boot `multi-user.target` instead of `initrd.target`.
    The reason is that `systemctl set-default` modifies `/etc` while `ln_r`
    modifies `/usr`. And so the `set-default multi-user.target` in 00systemd
    takes priority over the `ln_r initrd.target` in `01systemd-initrd`.
    
    Thanks Jonathan Lebon for spotting this.
