bind: security bump to 9.11.4

Fixes CVE-2018-5738: When recursion is enabled but the allow-recursion
and allow-query-cache ACLs are not specified, they should be limited to
local networks, but they were inadvertently set to match the default
allow-query, thus allowing remote queries.

Update license file hash; copyright year update.

Add reference to tarball signature key.
