We had to change this for Thunderbird 52 due to the following Mozilla
bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1367672

The correct locale format in Thunderbird is xx-yy (not xx_yy). However,
Thunderbird seems to be unable to cope with additional parameters in the
locale like ".UTF-8".

I would expect that the following patch fixes the issue.
