Fix ownership change in stage-output

If the stage_dir/logs directory was a symlink, Ansible would refuse
to perform the chmod.  However, if we tell Ansible that it is a
directory, it's fine.  This (perhaps curiously) does not tell
Ansible to turn the symlink into a directory.  It just tells it
that everything is okay.
