jdeps --check throws NPE when the module descriptor has missing dependences. This patch fixes jdeps --check option to report a module with missing dependences as other jdeps options.
This patch applies on the top of the patch for JDK-8229396 [1]. Thanks Mandy[1] http://mail.openjdk.java.net/pipermail/jigsaw-dev/2020-January/014342.html
