hwmon/coretemp: Cosmetic: Rename internal variables to zones from packages 

Syntax update only -- no logical or functional change.

In response to the new multi-die/package changes, update variable names to
use the more generic thermal "zone" terminology, instead of "package", as
the zones can refer to either packages or die.
