[PATCH] systemd: add support initial systemd service files

["Luis R. Rodriguez" <mcgrof@do-not-panic.com>]

From: "Luis R. Rodriguez" <mcgrof@suse.com>

I've tested these on an OpenSUSE Tumbleweed source install.
They are based on the ones from OpenSUSE but slightly modified.
In particular the xencommons systemd service file was changed
to not require the capability file to exist prior to
initialization as the xencommons service is the one that
provides it by mounting xenfs for you.

If you don't specify a prefix you will end up with the services
files under /usr/local/lib/systemd/system/ by default, which
systemd does look for. Distributions are expected to provide their
/usr/ prefix to end up in the more generic location upon distribution
install at /usr/lib/systemd/system/.
