    Babel option for Vietnamese is called "vietnamese"
    
    The renaming happened in 2013. Contrary to what is stated in the
    babel-vietnamese manual, option "vietnam" does not work anymore.
    
    Also, the special care is note needed anymore, since language options
    are not hardcoded anymore in babel.
    
    Fixes: #10743
