JDK-8212970 - TZ database in "vanguard" format support
Description
There's a piece of hacks in sun/util/calendar/ZoneInfoFile.java, to tweak endOfDay rules for Asia/Amman and Africa/Cairo. These hacks are no longer needed as secondOfDay holds correct values, even beyond the end of day. It is a leftover of JDK-8212970.
In fact, the hacks would be problematic, say if Jordan had a DST starting rule at "lastFri & startTime= 0:00", it would be incorrectly translated into "lastThu & startTime=24:00"
