nip.io has full suite of nameservers

Browse Source 
nip.io has the complete set of NS records that sslip.io has. Previously
all the nameservers had only sslip.io records, e.g. ns-ovh.sslip.io.
With this commit, we now duplicate the nameservers, so now there's an
ns-ovh.nip.io as well. This also includes the "wildcard" record,
ns.sslip.io.

This unlocks the ability to use the shorter "nip.io" domain for certain
lookups, e.g. "dig txt @ns.nip.io ip.nip.io", whereas previously I'd
have to do "dig txt @ns.sslip.io ..."
