doc: afsd -settime and -nosettime are obsolete

Update the afsd man page -settime and -nosettime options, which are obsolete
and no longer have any effect.  Use the same wording as the other obsolete
options in the afsd man page.  Keep the recommendations to use the time keeping
daemons provided by the operating system to maintain the system time.
