dns/dnsmasq: regression fixes from upstream Git
Apparently there are situations where dnsmasq 2.83 can confuse
its peers or sockets, and the upstream Git contains fixes for them.
These four fixes essentially take dnsmasq to 2.84test3.

dns/dnsmasq: upgrade to v2.84 (regression fixes)
Upstream blessed v2.84 rc2 (which 2.83_1 effectively already was)
into v2.84 release, so take it (and patch the upstream bug of
leaving "rc2" in the version out).
