Export dependency for "javax.jms.api" in org.jboss.genericjms module

More info in WFLY-4642.

If deployment with MDB has dependency to module "org.jboss.genericjms" then module "javax.jms.api" is not loaded for the deployment and deploy fails.

This is a change in module loading behaviour against previous versions of Wildfly/EAP and complicates migration/usability.

We can avoid this by exporting "javax.jms.api" dependency in "org.jboss.genericjms" module. It should look like:

<module xmlns="urn:jboss:module:1.3" name="org.jboss.genericjms">
 ...
    <dependencies>
     ...
        <module name="javax.jms.api" slot="main" export="true"/>
     ...
    </dependencies>
</module>
