Skip Oracle databases in HQLScrollFetchTest.testScroll

HQLScrollFetchTest.testScroll fails on all Oracle Databases when hibernate core is run for EAP 4.3.0_CP10.
Reason:
The fix tested by HQLScrollFetchTest.testScroll relies on results being ordered consistently. Because some databases do not return sorted data (such as H2) you should explicitly apply "order by" for ScrollableResults result ordering.

refer Jira JBPAPP-5897.
This test should be skipped for all Oracle Databases.
