jpackage can use external runtime through `--runtime-image` cli option and not invoke jlink. 

Would you consider adding an error message to jpackage if it detects jlink tool is not available as an alternative to not including jdk.jpackage module in `ALL-DEFAULT`? Seems like a more generic solution.
