xen-tools: correct xencommons initscript for systemd
xen-tools: correct xencommons initscript for systemd

commit [xen-tools: don't declare xencommons as an initscript for
systemd] was wrong in an amazing two ways. It has an extranenous
} and it has inverted logic.

The result is that xencommons is not being properly declared as
an initscript for sysvinit, and hence we don't fully boot. It
isn't a problem for most systemd configurations, so we were
booting as the initscript wasn't firing.
