meta-openpower: fix logging in first-boot-set-*

Makes the showing of the warnings  in the first-boot-set-mac.sh and
first-boot-set-hostname.sh are same

If the script runs manually the warning messages are shown on STDERR.
If the script runs as a systemd unit the warning messages  are shown in
a system journal.

(From meta-openpower rev: f80fbdb15330f694e4f80992470605d46b998efd)
