Set locale in C programs so l10n works (RHBZ#559962).

This commit adds the calls to setlocale &c to all of the current
C programs.

It also adds l10n support to hivexget and hivexml which lacked them
previously.

To test this, try:

LANG=pa_IN.UTF-8 guestfish --cmd-help

(You can only do this test after installing the package, or at
least the 'pa.mo' mo-file in the correct place).
