lib/time, time, time/tzdata: use slim tz data format

Follow-up for CL 261363 which had to retain the fat tz data format due to failing test. The reason for the failed tests was that when caching location data, the extended time format past the end of zone transitions was not considered. The respective change was introduced in (*Location).lookup by CL 215539. This slims down zoneinfo.zip (and thus also the embedded copy in time/tzdata) by ~350KB.
