Improve cpusensor performance

The cpusensor service is still making some redundant accesses for
reading hwmon attributes on every scanning. Actually, threshold
update is needed only when CPU package's Tcontrol target is
changed so this commit make it do that only when Tcontrol value
is changed.

Tested:
  Compare cpu resource consumption of cpusensor service using top.
  It should eat less cpu resources than before.
