Android: activate tst_qfactoryloader

- Use QT_ANDROID_EXTRA_PLUGINS to specify a correct plugins directory
- Update plugin names on Android to match the expected format
- Add explicit dependency on the plugins, so that they always get built
  and included in the APK
- Update the test code to respect the fact that plugins are packed
  differently on Android.

All these steps allow to enable this test for Android in CMakeLists.txt
