Log Message:
Enable VerifyHostKeyDNS (SSHFP records verification) from DNS for hosts
under NetBSD.org domain.

Multiple TNF hosts have an up-to-date SSHFP record inside the DNS.
This offers a second channel verification for host key fingerprints
(weaker than known_hosts, but spoofing a host on first connect would
also require DNS forgery).

This can provide a trusted second channel (like DANE TLSA records) once
DNSSEC gets more widely used, but for now it is purely informational.

No regression expected, except that the ssh client will print a message
upon first connect to confirm/infirm that it got a correct SSHFP record
from DNS.

Only done for NetBSD.org domain, SSHFP are sadly more an exception than
the rule.

Notified on netbsd-users@, no objection after a week -- committed.
