Correct the raw offsets in the time zone index for a few zones.
ZoneCompactor was using the system time zone database to get the offsets
instead of using the data it was compiling, so for newly added or recently
changed zones the index could be inconsistent with the data.
Affected zones: San_Luis, Casey, Davis, Mawson, Kathmandu, Novokuznetsk
