Fix /opt/android folder permission (#6207)

Summary:
The [job](https://github.com/pytorch/executorch/actions/workflows/android.yml) starts to fail after https://github.com/ReactiveCircus/android-emulator-runner/releases/tag/v2.33.0 released 3 days ago.  The fix would be to make `/opt/android` owned by CI user instead of root.
