    autofs-5.0.6 - fix ipv6 name lookup check
    
    The host address must be used when the host name has multiple
    addresses since we need to mount the specific host and so that
    it is known what host log entries refer to.
    
    But the check for multiple addresses can be wrong because there
    is no distinction between ipv4 and ipv6 addresses. Change the
    check to use the host name when mounting if neither the ipv4
    or the ipv6 addresses have more than one record.
