Fix broken LayoutableShadowNodeTest after Modal fix. (#52130)

Summary:
Pull Request resolved: #52130

After D73948178, Modals now need to access JNI to get the dimension of the
screen to properly position the modal on first rendering.

Before my change, the Modal was positioned in 0,0 (which is the default
behavior for CXX).
I'm suppressing this test for Android, as it will keep on running with the
previous behavior for CXX.
