This causes get_unused_port_or_die to try different port numbers in each
concurrently running tests, and consequently enables some parallelism of test
processes.

On Linux with disable_ipv6=1, we can create sockets bound to [::]:port, yet
connecting to that address triggers an Unreachable error. Since IPv6 is
useless on such machines, it's cleaner to turn it off than expose users to a
half-broken state.

tests on machines that support AF_INET6 sockets bound to ::1.
Listening on :: or connecting to a mapped address should always work.
