This should basically "just work" now, but I'd like to do a bit more
testing before shipping a "systemd" mkinitcpio hook.

I did the minimal work to allow /usr/lib/systemd/systemd-shutdown to
be used instead of our current /shutdown script, so this should work
with v198.

However, I think we want to improve the systemd shutdown logic to make
it a bit more elegant before using it by default:

 * It should be a bit more clever about the order in which it tries to
unmount things.
 * It should avoid printing ugly warnings from shutdown in the real
root when the problems will anyway be solved in the shutdown ramfs.
 * Lastly, we should probably optimize the whole process by giving up
early in the real root and jump into the shutdown ramfs as soon as
possible.

Patches welcome  :-)

Cheers,

Tom
