cpi: Introduce new udev rule and integrate with systemd unit

Browse Source 
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.
