Set InterfaceHandle correctly for methods inherited from Object

When calling lookup().getVirtual() on an interface for a method in
java.lang.Object, don't check the itables for the method.  Instead, set the
methodIndex to -1 and return the concrete method.

If the method cannot be found,  throw an exception.
