> Tasks implicitly pick up shared libraries added to the job because the task launch context
explicitly adds the container working directory to LD_LIBRARY_PATH.  However the same is not
done for the AM container which is inconsistent.  User code can run in the AM via output committer,
speculator, uber job, etc., so the AM's LD_LIBRARY_PATH should have the container work directory
for consistency with tasks.
