UUCP is no longer contained in the base system, so its home directory

does not require special permissions.  The security(8) scripts hates
group-writeable home directories, so remove the needless permissions.
Issue noticed by Andrew Fresh <andrew at afresh1 dot com>.
If i understand naddy@ correctly, this is unlikely to harm even UUCP users.
