[PATCH] backup.pl: Create the new unbound user and group when doing a restore

[Adolf Belka <adolf.belka@ipfire.org>]

- With the introduction of the unbound user and group, when a restore is done from a
   earlier backup when user and group nobody were used then the unbound user and group
   are removed as passwd and group are backed up.
- Using the entry already present for the dhcpcd user and group I cre4ated this patch.
- Not 100% certain it is the correct way to do it, as I am not sure about if a restore
   is done where the unbound user and group already exist but presumably the same effect
   occurs with the dhcpcd user and group.
