Review request 8153895 (proxy) redundant read edges to superinterfaces of proxy interfaces

[Mandy Chung]

Peter spots the redundant read edges are added to dynamic module when creating 
a proxy class.   Proxy class does not access super interfaces of proxy 
interfaces.   I have verified this simple patch with all core tests and JCK api 
tests.
