Fix github worklow for Android tests

- The github workflow fails when running android tests.
- The workflow is trying to launch an x86 emulator on aarch-64 (macos-latest) host.
- The macos-latest system seem to be used originally as it supports
  hardware acceleration.
- This is no longer recomended, and ubuntu-latest host can handle the
  same and be faster than macos-latest.
