Exclude JUnit 4 from Whiteboard and update imports to JUnit 5 (#2534)

* Exclude JUnit 4 from Whiteboard and update imports to JUnit 5

Excludes the transitive JUnit 4 dependency from the Aries JAX-RS Whiteboard.
The Whiteboard should not have a compile scope dependency on JUnit so I've created https://github.com/apache/aries-jax-rs-whiteboard/pull/135 to fix this.
The wrong scope has resulted in some tests using JUnit 4 imports which is also fixed in this PR.
