dns: Always enable DNS request for our DNSPort

Commit 41cc1f612bd2112ab7cec0cc4fdeb68c26e231bf introduced a "dns_request"
configuration value which wasn't set to 1 for an entry connection on the
DNSPort leading to a refusal to resolve the given hostname.

This commit set the dns_request flag by default for every entry connection
made to the DNSPort.

Fixes #20109
