This fixes the problem of getent ahosts localhost returning 127.0.0.1
_twice_ on systems that have no ipv6 interfaces up (hence are regarded
as ipv4 only by the lookup code), but still have localhost entries for
::1 and 127.0.0.1 in /etc/hosts (like most current systems).

Remapping ::1 to 127.0.0.1 is bogus when /etc/hosts is correct.
