    w(1): fix libxo output being locale dependant
    
    by being locale dependant the json export is invalid in locales where
    the separator for float is a comma.
    The Json and the XML are invalid for login-time when days contains
    contains characters which are not unicode.
    
    Forcing locale to be C, makes this json and xml output valid and also
    identical accross locales, so reliable for parsers
