LibTimeZone: Add an API to retrieve the system's current time zone

This is a wrapper API around the POSIX tzset / tzname information. It
is to help ensure that tzset is invoked before accessing tzname.

LibTimeZone: Begin generating GMT offset rules for each time zone
...
This is a rather naive implementation, but serves as a first pass at
determining the GMT offset for a time zone at a particular point in
time. This implementation ignores DST (because we are not parsing any
RULE entries yet), and ignores any offset patterns of the form "Mon>4"
or "lastSun".
