[OE-core] [krogoth] systemd network service fails to start on boot

[Kristian Amlie]

Hey,

on our krogoth build the systemd network service does not start, and it
seems to be because of missing users, which has already been fixed on
master. I've cherry-picked the two patches that fixed the problem for
us. Note that they are not written by me, but by other people on this
list. I hope they can be applied to krogoth.

Regards
