Copy security attributes of root skeleton

The xattr of the root of the skeleton are now
copied when the home directories of users are
created.

This patch is needed to set default Smack attributes
to home directories.

For example, for automatically setting the Smack access of home
directories to User::Home and their transmute value to TRUE for
the newly created users, it is now enough to issue

 chsmack -a User::Home -t /etc/skel

where /etc/skel is the skeleton directory used when creating users.
