Add a build rule for files used by mdns

mdns may be imported in other non-AOSP projects as a library, along with
its dependencies from net-utils-device-common. While all of
net-utils-device-common may not build against system API, this requires
the files used by mdns to build against system API.

Add a library to allow checking that the dependencies can still build
against system API.
