apk: Include recursive libraries via gradle as well (#140)
The `gradle` build was only including the target library from `cargo`, but not any (in)direct dependencies like `libc++_shared.so`. Move the logic where we recursively scan all libraries, and pass the result to the `gradle` builder in addition to the existing `apk` builder.
