Remove the syslog stuff, and allow various return values
in uu_lock(). Add uu_lockerr() for turning the results of
uu_lock into something printable. Remove bogus section in man page
about race conditions allowing both processes to get the lock.
Include libutil.h and use uu_lock() correctly where it should.
