Make systemd as default system and service manager for poky, needs autobuilder changes also.
I recently noticed one inconsistency with our systemd setup - we don't seem to set up a default network, so network interfaces (especially wired interfaces, en*) are not brought up by default, which is a bit annoying.
I've filed bug 13057 to cover the systemd network configuration issue.
In the end we made systemd the default for poky-altcfg so we can consider this complete now.
