RFR: JDK-8259395 Patching automatic module with additional packages re-creates module without "requires java.base" [v4]

[Johannes Kuhn]

> Simple fix - one line change: https://openjdk.github.io/cr/?repo=jdk&pr=2000&range=00#sdiff-0.
> 
> Most of the changes come from an additional test that fails without this fix:
> 
>      Error: Unable to load main class somelib.test.TestMain in module somelib
>     	java.lang.IllegalAccessError: superclass access check failed: class somelib.test.TestMain (in module somelib) cannot access class java.lang.Object (in module java.base) because module java.base does not export java.lang to module somelib
> 
> As described in JDK-8259395.
> You can view the output of the test without patch here: https://github.com/DasBrain/jdk/runs/1668078245
> 
> Thanks to @AlanBateman for pointing out the right fix.
