This test uses `bin/jlink`, which is not provided on static JDK. There are other tests that require tools in `bin/`. Those are not modified by the current PR to skip running on static JDK. Those can be done after the current change is fully discussed and reviewed/approved.

That's okay with me. I'm hoping Magnus will jump in when he gets a chance as he has experience with the "other" static build configurations.
