[FIX] Launcher APK does not enable PythonService

When using the Launcher APK, apps using PythonService got "PythonService not found" on `.service.start()`:

```
01-11 05:43:10.866  1385  2905 W ActivityManager: Unable to start service Intent { cmp=org.kivy.pygame/org.renpy.android.PythonService (has extras) }: not found
```

This PR:
- Enabled PythonService for `launcher` APK too.
