Kevin Darbyshire-Bryant 3bef96ef18 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
