[tz] 2014 DST changes in Egypt, again

[Tim Parenti]

In reviewing the recent changes, I noticed that three of the four
transitions for Africa/Cairo in 2014 were defined as occurring at 24:00,
while a third was defined at 23:00s.  Looking back, I noticed there is a
lot of inconsistency in this regard, which doesn't seem to have been
intentional.

The attached patch replaces all transitions to standard time in
Africa/Cairo at 23:00s with 24:00; it also redefines 2010 Ramadan
transitions which occurred at 0:00 as occurring at 24:00 of the previous
day.  I haven't touched more general transitions at 0:00 or 0:00s since
many of those allow rules to be defined succinctly (e.g., lastFri 0:00).
 This patch did not change the output of zdump in my tests.
