Rather than having MAC policies explicitly declare what object types

they label, derive that information implicitly from the set of label
initializers in their policy operations set.  This avoids a possible
class of programmer errors, while retaining the structure that
allows us to avoid allocating labels for objects that don't need
them.  As before, we regenerate a global mask of labeled objects
each time a policy is loaded or unloaded, stored in mac_labeled.
