qom/object.c: Allow itf cast with num_itfs = 0
num_interfaces only tells you how many interfaces the concrete child class has
(as defined in the TypeInfo). This means if you have a child class which defines
no interfaces of its own, but its parent has interfaces you cannot cast to those
parent interfaces.
Fixed changing the guard to check the class->interfaces list instead (which is
a complete flattened list of implemented interfaces).
