[LTP] [PATCH 1/5] net/dhcp: Add support for wicked

[Petr Vorel]

wicked network configuration daemon conflicts with dhclient. In order to
use dhclient, it requires wicked to be disabled.

daemonlib.sh currently doesn't have support for enabling detection.
While we could add support for it, wicked is used only in openSUSE/SLE
with systemd let's ignore non-systemd versions.

Fixes: openSUSE/SLE using wicked
