blackbox: do not translate the log messages

User 'timeless' in irc mentioned that having the blackbox be
translated would result in logs that:

- may be mixed language, if multiple users use the same repo
- are not google searchable (since searching for english gives more
  results)
- might not be readable by an admin if the employee is using hg in
  his native language

And therefore we should log everything in english.
