Add integration tests for the new Log4j 2.x agent in Log4j 1.x compat
mode using the current 'log4j' domain, use the new configure switch
'--enable-test-java-agent-log4j2' to enable it or
'--enable-test-java-agent-all' to enable all Java agents tests.

To run only this new test, use this command :

  cd tests/regression && make check TESTS="ust/java-log4j2/test_agent_log4j2_domain_log4j"
