Error message talks about “family 0”, but does no explain what 0 is

[AlexDaniel]

This is a late followup on this MoarVM pull request: MoarVM/MoarVM#700

Before the change the error message was:

Failed to resolve host name 'perl6.or'. Error: 'Name or service not known'

Now it says:

Failed to resolve host name 'perl6.or' with family 0. Error: 'Name or service not known'

I raised this question some time ago: https://irclog.perlgeek.de/moarvm/2017-10-21#i_15334051

Which resulted in this:

<jnthn> Probably worth trying to map it into a string, I guess just a switch/case and fall back to "family N" if it's not one we have a mapping for
<eater> I guess right now that would be the best option ye

The change has to be done in MoarVM, but given that we observe the issue on the high level, I guess this tracker is appropriate?
