Apply "chown", but very conservatively

In the interest of not breaking people, only chown the root directory when we've determined WordPress is not installed, the permissions on the directory are root:root/0:0 (and it is thus likely the directory was "helpfully" auto-created by Docker), and we are running as root (and thus able to chown).
