Fix package to match log4j2.xml packages attribute

Rationale

@labkey-willm flagged a log4j2 error on Tomcat standalone which pointed out that this class is in the wrong package for that deployment scenario

I agree the path and declared package should match, but I'd prefer to use the logging subpackage or get rid of it completely. I guess my attempt at moving it in the original FB didn't go well.

Since log4j2.xml has now been updated in the docker PR, this class and SessionAppender will disappear once we're embedded-only, and branch time is quickly approaching, I'm going to leave it like this for now. We can clean up the logging package in a subsequent PR if we want to.
