Sadly, I didn't get to this yesterday and I spent most of today
flying cross-country. Because we never ditched the libsystemd provide on
systemd, we can do this piecemeal. I'm pushing a split of util-linux
into testing tonight, and I'll handle the libsystemd/systemd split
tomorrow or Wednesday when systemd 211 is released.

As discussed on IRC, this is only going to be a runtime split.
libutil-linux will only contain the dynamic libs for libuuid, libblkid,
and libmount. Similar for systemd -- libsystemd, libudev, and the compat
libs.
