    Remove Flatpak test locale hack, just use en_US.UTF-8 for now
    
    FDO 19.08 runtime now includes C.UTF-8 locale, but since Fedora
    now ships one that collates high-bit chars, it differs compared
    to Debian et al's and FDO.
    
    As a result, just use en_US.UTF-8 for now, probably until glibc
    actually ships it and so they all agree.
