Fix compatibility with IO Platform

https://build.spring.io/browse/INT-MJATS41-492

The SI-4.3 has been upgraded to openJpa-2.4.0 for Class Transformation on Java 8 support.
 The Spring IO is still on openJpa-2.3.0.
 Using version in the agent pattern isn't good idea to distinguish the proper jar, because IO does version re-mapping at runtime.
 Change the pattern to consider version as is, but don't match other openJpa jars (transitive required dependencies) in the classpath, e.g. `openjpa-persistence-jdbc` .
