When removing a user's home directory, if the directory is a ZFS dataset, it cannot be removed. If the directory has been emptied, use "zfs destroy" to destroy it. This complements the automatic dataset creation in adduser. Note that datasets within the directory and snapshots are not handled, as the complete path is not constructed. While here, add waitpid() calls to rmat() and pw_user_del(). Reviewed by: des Differential Revision: https://reviews.freebsd.org/D45348
