[OE-core] [PATCH v3 2/2] systemd-conf: configure wired network with dhcp

[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

Add a configure file for systemd.networkd to configure wired network
interfaces with dhcp. It works with common network interfaces such eth0
and eno1. And do not install it for qemu bsps.
