Use a known well behaved DNS server.

/CC @nodejs/testing

Fixes: #25870

P.S. ATM the DNS server configured on one of our CI workers, fails for the domain name used in this test:

root@test-rackspace-ubuntu1604-x64-1:~# nslookup xn--strae-oqa.de
;; Got SERVFAIL reply from 119.9.60.62, trying next server
Server:         119.9.60.63
Address:        119.9.60.63#53

** server can't find xn--strae-oqa.de: SERVFAIL

this causes the daily CI test of master to fail: https://ci.nodejs.org/job/node-test-commit-custom-suites/

Lookup works fine when directed to use 8.8.8.8

root@test-rackspace-ubuntu1604-x64-1:~# nslookup xn--strae-oqa.de 8.8.8.8
Server:         8.8.8.8
Address:        8.8.8.8#53

Non-authoritative answer:
Name:   xn--strae-oqa.de
Address: 81.169.145.78

node-daily-master failed today for the sixth day in a row due to this. Would love to fast-track this. 👍 here to fast-track.

EDIT: Withdrawing pending outcome of the "use DNS*_SERVER" conversation. Since node-daily-master only runs once a day, we'll live with the red job another day or two if we have to.

https://ci.nodejs.org/job/node-test-commit-custom-suites-freestyle/5084/ seems like this doesn't fix the issue 🤔.

The dns.setServers() method affects only dns.resolve(), dns.resolve*() and dns.reverse() (and specifically not dns.lookup()).

So I patched the hardware.
