dnsmasq: bump to v2.80test7 

Bump to latest test release:

3a610a0 Finesse allocation of memory for "struct crec" cache entries.
48b090c Fix b6f926fbefcd2471699599e44f32b8d25b87b471 to not SEGV on startup (rarely).
4139298 Change behavior when RD bit unset in queries.
51cc10f Add warning about 0.0.0.0 and :: addresses to man page.
ea6cc33 Handle memory allocation failure in make_non_terminals()
ad03967 Add debian/tmpfiles.conf
f4fd07d Debian bugfix.
e3c08a3 Debian packaging fix. (restorecon)
118011f Debian packaging fix. (tmpfiles.d)

Delete our own backports of ea6cc33 & 4139298, so the only real changes
here, since we don't care about the Debian stuff are 48b090c & 3a610a0

Subject: [PATCH 2/2] Change behavior when RD bit unset in queries.
Change anti cache-snooping behaviour with queries with the
recursion-desired bit unset. Instead to returning SERVFAIL, we
now always forward, and never answer from the cache. This
allows "dig +trace" command to work.
