Convert remaining die*(BUG) messages

These were not caught by the previous commit, as they did not match the
regular expression.

While at it, remove the localization from one instance: we never want
BUG() messages to be translated, as they target Git developers, not the
end user (hence it would be quite unhelpful to not only burden the
translators, but then even end up with a bug report in a language that
no core Git contributor understands).
