wayland: Handle get_subsurface() with a role-less parent surface

The order of role creation is undetermined, so we can't account that
the parent surface will have a role (and an actor) at the time of
creating the wl_subsurface role for a child surface.

So we must do it both ways, add the subsurface as a child on
get_subsurface() if the parent already got a role, and lazily add
child subsurface actors to the current one if the parent surface got
it at a later point.
