dnsproxy: send a response including queries
This is revert patch of https://git.kernel.org/pub/scm/network/connman/connman.git/commit/?id=d74bb4a97224b6382ae2f542fe3751b1904e9b2e
Some DNS API checks a query field of DNS response to verify the response.
So, DNS resolving delay is often caused in case of DNS error.
This patch makes dnsproxy send the 'whole' packet.
