Ignore psys domain for CPU power sensor

Browse Source 
psys domain is a system domain which aggregates all system power. This requires
hardware support and configuration by OEMs. There can be multiple psys domains
in servers. psys domains are present at the same level as package domains in the
powercap/intel-rapl sysfs. This is not just CPU related power.

For CPU power sensor just use package level without adding energy values from
psys domains. So, skip adding psys energy value to $total_energy.
