ntdll: Return correct time zone names for Asia/Tokyo and Asia/Yakutsk.
Without this change, for Japan, Wine returns "Korea Standard Time",
not "Tokyo Standard Time" as seen in Bug 42719.
Actually, this is a regression by
d666143f880f9e19849f8f2b520dc059a11750d1.
The new code relies on offsets from UTC and DST change timings. However,
Northeast Asia regions don't use daylight saving time. Thus, Wine can't
distinguish between these regions.
