Noticed on RHEL CoreOS that the CPI service failed to start with:
"Cannot access lock file: /var/lock/cpictl.lock"
This was a timing issue where /var was not created yet and the symlink
to /run/lock was not present. Add sysinit.target to fix this.
This fix has been tested with RHEL CoreOS.

The cpi service unit requires an Install section to tell systemd
when to start the cpi service. Add an install section and start
cpi for the multi-user target.

Add a new udev rule that is triggered when a KVM VM is started
on the system the very first time. This rule reports over the
sysfs CPI kernel interface that the system is a KVM host.
Currently the cpi.service systemd unit already works with
the CPI sysfs interface. Introduce a new internal utility
script "cpictl" that is used by both the udev rule and
the systemd unit to guarantee coordinated access to the
kernel CPU interface.
