LogSupport should infer correct caller frame

The org.eclipse.angus.activation.LogSupport uses a JUL logger under the hood but calls the standard log methods. This will cause all log records to report a caller of `LogSupport.log` while correct is not helpful.

What should happen is the LogSupport should be updated to find the caller of LogSupport and that frame should be passed to JUL using the log precise methods.
