Exclude cxf-bundle-jaxrs from eap63 and wildfly8 wars

I think the cxf jars should _not_ be included in the WEB-INF/lib as the war already depends on CXF module from EAP/WildFly. I am however quite new to this and I am not 100 % sure this the correct solution, so creating PR for review instead of directly committing the changes.
