[KMTESTS:EX] Use stricter checks for the UUID returned from ExUuidCreate.

Browse source 
* Check the entire version field
* Check the variant field
* Accept RPC_NT_UUID_LOCAL_ONLY, which is sometimes returned by Windows
* Repeat the test to show that these things happen every time

Based on a patch by Serge Gautherie.
