Modify JBossWS build to support jboss510 target container only

Permaine / Fernando now require us not to refer container integration artifacts for containers that are not actually used, ie. 500, 501. That's required to reduce the number of brew builds. Those artifacts, despite being referenced by the build, are actually not used for EAP5.
To achieve this, we need to fix the whole build in order to support jboss510 target only (the one used for EAP5).
