Description of problem:

Livecd creation failed due to udevadm being missing. it ended up that the only reason udevadm was being pulled in was NetworkManager having a dep on udev. hoever with commit http://pkgs.fedoraproject.org/cgit/rpms/NetworkManager.git/commit/?id=ce85c6f3ef984d17cfc3cae7f883ae3521ebb961 the Requires: udev was removed resulting in udevadm no longer being available in the installer environment for anaconda to execute  as anaconda calls the command it needs to add a requires on udev or systemd-udev in order to make sure a command it executes is available
