Test rogue plugin trying to override a ROM based plugin by

duplicating the legitimate DLL's implementation UID (different

interface UID so that ECOM not treat it as an update).

@SYMTestCaseID			SYSLIB-ECOM-CIT-3161

@SYMTestCaseDesc	    Copy a rogue plugin to C drive. This plugin duplicates the

						implementation UID of a built-in dll. Test if the rogue

						plugin will over shadow the built-in dll.

@SYMTestPriority		High

@SYMTestActions			1. copy the rsc and dll of the rogue plugin to C:

						2. Use the CreateImplementation API which does not specify

						   the i/f UID to instantiate the built-in implementation.

						   Test the instance works normally.

						3. Repeat 2 but instantiate the pointer as the rogue plugin

						   class. Pass NULL as the initialising param in the call

						   to CreateImplementationL. Because the actual plugin returned by

						   ECOM needs this initParam, KERN-EXEC 3 panic occurs.

@SYMTestExpectedResults	The test must not fail.
