Don't sort passive localhost addresses, so that IPv6+IPvv4 remains first and
IPv4-only, last
I don't think it ever makes any sense for us to ever try to sort passive
addresses: we always generate them IPv6+IPv4 first and IPv4-only last, with at
most two adresses and possibly only one if we asked for a specific family.
Since the former is always preferred, it doesn't make sense to try to sort
them.
The only doubt is whether to generate both when the first covers both; I'm not
when dropping the latter is safe, so I'm leaving that unrelated decision out
for now.
Any reason to not go with this patch?
