Consider removing any dependency on Application Services

Application services is a collection of components Mozilla uses with Firefox to provide online services. Basically, stuff we disable at runtime.

For some reason (reproducibility? F-droid?) we build it instead of treating it like any other Java dependency, even though we patch only the copy of NSS it builds. And it's very hard to do it offline.

Not only we don't use these components, but the result is giant: only the native code is 12MB (4.2MB compressed).
