ProfileService client dependency needed for jboss-as-client

After 6.0.0.M1, the client jar for the ProfileService is no longer included in the jboss-as-client POM. Since it was not explicitly called out in this POM, it must have been included earlier through transitive dependencies that have since changed. The required fix is to just add the client classifier artifact for ProfileService to the parent POM and the client POM.
