Servlet protocol should relocate ejb-jar.xml if necessary when generating a web archive

If the test archive is an EJB JAR (a JavaArchive that has a META-INF/ejb-jar.xml file), the protocol deployment packager should relocate the ejb-jar to the WEB-INF directory of the web archive it generates. Otherwise, the ejb-jar.xml file is not processed.

Here's an example test case:

If there are other ways to accomplish the same task, feel free to suggest an alternative approach.
