Gradle APKs include all architecture libraries instead of just the target

AAR files may contain multiple architectures and Gradle is including them all instead of filtering them to only include the active architecture in the APK.

1. Create blank project
2. Enable Gradle
3. Package for Android
4. Go to the Intermediate/Android/APK/gradle/app/src/main/libs and create a arm64-v8a directory and copy any file into it with a .so extension
5. Go to the Intermediate/Android/APK/gradle directory and run "rungradle.bat :app:assembleDebug"
6. Open the Binaries/project-armv7-es2.apk as a zip and check if the libs contains the arm64-v8a (it should have been filtered out)
