Alembic: when exporting flattened, always check parent for animation

When exporting to a flattened "hierarchy", the animation of the parent
(in Blender) will not be known to the Alembic file. In this case,
whenever an object is moving, it needs to be treated as animated, even
when it's through the animation of its parent.
