Remove references to jboss logging appenders (and levels) from log4j.xml files of testsuite

With the upgrade to 3.0.0.Beta2 of jboss-logging in AS trunk, we have started seeing:

These classes no longer exist in this version of jboss-logging. Effectively, there's no logging going on, on the client side.

In any case, we don't need any JBoss specific appenders in that log4j.xml. Just falling back on log4j specific appenders and log4j specific appenders should be enough. Update the log4j.xml file accordingly.
