fix volume root permissions

Make volume on the host to originate at /vol/name/data, not /vol/name,
so /vol/name/data mode can be set to 755 so inside container non-root
users can access it while preventing access on the host for non-root
users with 700 mode on /vol/name.

Fix volume SELinux labeling via running a dummy container with the
volume mounted with :z docker flag during volume initialization.

Fix setup password so it works.
