Include `::1 localhost` in /etc/hosts

[Treysis]

::1 is also in /etc/hosts in 20.04, but it's mapped to ip6-localhost,
not to localhost.

And that had been different in the past.

Haven't installed 22.04 beta so I don't know what will be the case for
22.04 but I also guess it's too late to still land such a change. Though
it'd be a pity if that's gonna be the default for another 2 years.

Cheers,

Trey
