TOOLS: Use file descriptor to avoid races when creating a home directory
When creating a home directory, the destination tree can be modified in various ways while it is being constructed because directory permissions are set before populating the directory. This can lead to file creation and permission changes outside the target directory tree, using hard links. This security problem was assigned CVE-2013-0219 https://fedorahosted.org/sssd/ticket/1782
