Rework error reporting/logging: although the SunOS documentation says

that ypxfr is supposed to log messages to /var/yp/ypxfr.log if it exists,
using syslog() makes more sense, especially since ypserv does the same
thing already. Try to use stderr by default, and use syslog() if stderr
is not a tty.

Also update the man page to reflect this change.
