Simon Kelley 31c91b40bd Handle SERVFAIL responses to DS queries better. ...

On 15/5/2023 8.8.8.8 was returning SERVFAIL for a query on ec.europa.eu

ec.europa.eu is not a domain cut, that happens at jrc.ec.europa.eu. which
does return a signed proof of non-existance for a DS record.
Abandoning the search for a DS or proof of non existence at ec.europa.eu
renders everything within that domain BOGUS, since nothing is signed.

This code changes behaviour on a SERVFAIL to continue looking
deeper for a DS or proof of its nonexistence.
