ipatests: fix TestInstalDNSSECFirst::test_resolvconf logic
The test test_dnssec.py::TestInstallDNSSECFirst::test_resolvconf
checks that /etc/resolv.conf points to the localhost and
fails on fedora33 because systemd-resolved is in place
(and /etc/resolv.conf contains 127.0.0.53).
The test logic needs to be adapted. When systemd-resolved is
used, the test can check the output of "resolvectl dns".
