Remove wildcard + dependency (#7172)

Should help with maven central sporadic failure:

```
Could not determine the dependencies of task ':instrumentation:hibernate:hibernate-3.3:javaagent:test'.
> Could not resolve all task dependencies for configuration ':instrumentation:hibernate:hibernate-3.3:javaagent:testRuntimeClasspath'.
   > Could not resolve javassist:javassist:+.
```
