dns-answer: preserve shared aliases when removing records

dns_answer_remove_by_rr() mutats the backing OrderedSet even when the answer
has multiple references. Callers such as trust-anchor revocation could thus
change snapshots held elsewhere in the resolver.

Clone a shared answer before removal.
