Description of problem:
When checking Fedora bug #1647464, I discovered recent dnsmasq does not reply correctly to DNS queries without recursion desired bit set.

Version-Release number of selected component (if applicable):
dnsmasq-2.79-4.el8+7.x86_64

How reproducible:
always

Steps to Reproduce:
1. systemctl restart dnsmasq
2. dig @localhost +norec localhost4.localdomain4
3.

Actual results:
; <<>> DiG 9.11.4-P2-RedHat-9.11.4-16.P2.el8 <<>> @localhost +norec localhost4.localdomain4
; (2 servers found)
;; global options: +cmd

Additional info:
This issue is not present in 2.76 version in RHEL7, so it makes regression after upgrade. It can break especially setups from other recursive resolvers querying dnsmasq, because they do that always without recursion. Current dnsmasq forwards all non-recursive queries to upstream server, even when it serves correct answer with rd bit set.
