fancontrol: Deal with moving hwmon attributes

Several kernel drivers have already moved their attributes from the
hardware device to the hwmon class device, and others will follow.
Teach fancontrol about this possibility and let it adjust the attribute
paths transparently.

Patch by Jean Delvare <khali@linux-fr.org>.
See <http://www.lm-sensors.org/changeset/6216>.
