dnsmasq: update to dnsmasq 2.77test1

Bump to dnsmasq 2.77test1 - this includes a number of fixes since 2.76
and allows dropping of 2 LEDE carried patches.

Notable fix in rrfilter code when talking to Nominum's DNS servers
especially with DNSSEC.

A patch to switch dnsmasq back to 'soft fail' for SERVFAIL responses
from dns servers is also included.  This mean dnsmasq tries all
configured servers before giving up.

A 'localise queries' enhancement has also been backported (it will
appear in test2/rc'n') this is especially important if using the
recently imported to LEDE 'use dnsmasq standalone' feature 9525743c

I have been following dnsmasq HEAD ever since 2.76 release.
Compile & Run tested: ar71xx, Archer C7 v2

+Subject: [PATCH] Consider SERVFAIL as a non-successful response
+
+Treat Servfail as a recoverable error instead of a hard error.
+
+A misconfigured dns forwarder upstream can return a Servfail faster than
+a correctly configured one.
+
+In the case of a dnssec misbehaving, it will misbehave on all correctly
+configured upstreams. In the case of a normal DNS query, the original
+behavior of dnsmasq here was more robust.
