Multiple locales: Use the correct 12-hour time formats (bug 10496).

Multiple locales: Use the correct 12-hour time formats (bug 10496).

It has been discovered that some locales use the 12-hour time formats but
do not use any AM/PM indicator thus making the time ambiguous.  This
commit adds "%p" wherever it was missing.  In some cases it has been
identified that a locale should use 24-hour time format rather than
12-hour.  All time formats come from CLDR but this commit introduces as
few changes as possible (for example, it tries not to change the time zone
display).  For the locales which are not supported by CLDR the consistency
with similar locales (which means the same language or the same country)
has been preserved: if the time formats were the same before the change
then they are still the same after the change.

The time format updates can be roughly summarized as follows:

* Most of the locales of Djibouti, Eritrea, and Ethiopia now use
"%l:%M:%S %p".
* Most of the locales of India and some surrounding countries (Bangladesh,
Nepal etc.) now use "%I:%M:%S %p %Z".
* Most of the Arabic locales now use "%Z %I:%M:%S %p".
* Ge'ez language (Eritrea and Ethiopia) now uses "%l:%M:%S፡%p" (note the
consistent use of Ethiopic wordspace character).
* Tamil (India) now uses "%p %I:%M:%S %Z".
* Chinese (Hong Kong) t_fmt now uses "%p %I<U6642>%M<U5206>%S<U79D2> %Z".
* Additionally, the following locales have been switched from 12-hour time
formats to 24-hour, according to CLDR: Arabic (Morocco), Maltese, Somali
(Kenya), and Tamil (Sri Lanka).
* Finally, the Bulgarian, Czech, and Slovak locales used 24-hour time
format correctly but their t_fmt_ampm field was not empty containing
12-hour time format which was incorrect so it is now replaced with an
empty string.
