Make sure that all non-root-owned binaries in standard system

paths are chflaged 'schg' to prevent exploit vectors when run
by cron, by a root user, or by a user other then the one owning the
binary.  This applies to most of the uucp binaries, cu, tip, and
man (man was already installed properly).

MFC will occur when approved.
