[WFCORE-4413] Fixing javax.api and javax.sql.api modules BC issues

I analyzed modules before and after the changes and I identified just two backward compatibility issues.
Who's volunteering to review this PR @bstansberry @jmesnil @darranl @kabir @jamezp ?

Looks like the failures and hang are the same as in #3725 so maybe not related to that component upgrade after all.

[darranl]

Aren't some of these modules supposed to be automatically generated in jboss-modules now or are these two not a part of that?

[ropalka]

There was implemented an ability to define dependencies on Jigsaw aka JPMS (Java Platform Module System) modules in module.xml (JBoss module descriptors). If there's a module referenced in module.xml that has no module.xml definition it is considered to be JPMS module and JBoss Modules implementation delegates to PlatformModuleLoader for not-found modules.
Also note that JPMS system is emulated on top of JDK8.

To answer your question neither javax.api nor javax.sql.api represent a JPMS module.
That is also the reason why these modules have been deprecated.
It is necessary to include missing module dependencies there explicitly @darranl .
