FreeBSD jails act differently than your average vm or similar
application container. All routing passes through one ip address,
which makes things like localhost or 0.0.0.0 resolve differently.
Introduce a helper that allows us to verify if we're in a jail
and another one for returning an ip address for localhost.
Also, skip one test instead of trading additional complexity
in common.js for one specific user scenario.
