util-linux-ng is now in the core repo

We have replaced util-linux, which is currently unmaintained, with util-linux-ng, a fork of the original project. After a brief period in the testing repo, this has now been moved to core, and pacman will ask you to confirm the package replacement. It is perfectly safe to do so.

Details on util-linux-ng are available here: http://userweb.kernel.org/~kzak/util-linux-ng/
