Export LC_ALL to solve date (and future) issues

FIXES #818 (I hope).

in #818, @mslavkov reported that date fails in the BG.UTF-8 locale, but
that LC_ALL=C resolved the issue.


Since we already export LANG=C, that would seem to indicate that LC_TIME
is overriding it.  LC_ALL is the safer (stronger) choice.
