resolved: set the DNSSEC OK (DO) flag
This indicates that we can handle DNSSEC records (per RFC3225), even if all we do is silently drop them. This feature requires EDNS0 support. As we do not yet support larger UDP packets, this feature increases the risk of getting truncated packets. Similarly to how we fall back to plain UDP if EDNS0 fails, we will fall back to plain EDNS0 if EDNS0+DO fails (with the same logic of remembering success and retrying after a grace period after failure).
