Fixes unit-prefork in online for me. Kendy suggested to also change the forced locale to en-US.UTF-8 instead of just en-US, but that caused: warn:i18nlangtag:32416:1:i18nlangtag/source/languagetag/languagetag.cxx:1369: LanguageTagImpl::convertLocaleToLang: with bAllowOnTheFlyID invalid 'en-US.UTF-8'. This reverts commit c3d25b8b74867b5b8419d09f6e362aa6c8eae34f.
