Add missing chmod()

Browse Source 
During shadowtcb_move() the directory is temporarily changed to be
owned by root:root with permissions 0700.  After the change is done,
the ownership and permissions were supposed to be restored.  The
call for chown() was there, but the chmod() call was missing.  This
resulted in the broken TCB functionality.  The added chmod() fixes
the issue.
