Ansible launcher: set keep-hierarchy on log copying

We don't set keep-hierarchy in the log publisher because it only
publishes one file.  But we're tacking on the full ansible
directory to that publisher.  We want keep-hierarchy set so those
files don't just end up in the root.  Modify that in our job
publisher transform.
