fix(dracut.sh): correct wrong systemd variable paths

systemdsystemconfdir usually expands to /etc/systemd/system, but the local
configuration of systemd-networkd, systemd-timesyncd, portablectl and systemd
users is saved into directories whose parent is /etc/systemd
(systemdutilconfdir).

Also add missing exports.
