Johannes Segitz reported two issues:
1) faxaddmodem, faxsetup, and probemodem create temporary directories in a way that is not secure due to a race condition.
2) The HylaFAX spool directory bin and etc subdirectories are not secure against uucp deleting and recreating scripts that root runs.
These changes address these two issues.
