Added dependency on jboss-marshalling-river

On my environment, some tests are failing due to "Could not find a marshaller factory for river marshalling strategy". It seems that the version of the JBoss BOM depends on a version of the JMX which is not properly pulling all the required dependencies, so, we have to pull it ourselves. Fixing this increased the number of tests executed (+147) and decreased the number of failures (-6): https://jenkins.kroehling.de/job/gatein-wsrp/33/testReport/ . Unfortunately, I couldn't find yet an official Jenkins job for WSRP that includes the execution of these tests based on master, only for products. 

Additionally, bumped the versions of Arquillian and Shrinkwrap.
