resolved: add complex test case

This new test case tries to resolve a couple of known domains, to verify the validation results. It talks to resolved
via the bus, thus comprehensively testing the whole shebang.

Of course, it requires network connectivity and a DNSSEC capable DNS server, hence this is a manual test.
