BHoliday: Remove, unused.

There isn't much use for a class that can only compute the dates of
two minor and one major holiday. Probably in the future the Locale Kit
could be extended to expose ICU holiday APIs, but seeing as that
is a less-used functionality, this can just be removed altogether
for now at least.
