dnsmasq: Update to 2.84test3

dnsmasq v2.83 has a bug in handling duplicate queries which means it may
try to reply using the incorrect network socket.  This is especially
noticeable in dual stack environments where replies may be mis-directed to
IPv4 addresses on an IPv6 socket or IPv6 addresses on an IPv4 socket.

This results in system log spam such as:
dnsmasq[16020]: failed to send packet: Network unreachable
dnsmasq[16020]: failed to send packet: Address family not supported by protocol

dnsmasq v2.84test3 resolves these issues.
