Disable verbose JacORB logging

Some of the QA tests that use JacORB and JDK 11 fail [1] because JacORB is using a version of the sfl4j logger that needs updating for JDK 11. Since JacORB is no longer actively maintained that means we cannot use with jdk 11. It might be possible to configure a different logger but since we are seeing other issues with JacORB it's probably not worth the effort. At some point we will stop testing against this ORB.

For now the plan is only enable logging for fatal errors. We could turn off logging completely but that may obscure fatal errors.
