#14416: conditionally add LOG_AUTHPRIV facility and LOG_ODELAY to syslog.

Unlike the other facilities, we don't use a fallback for AUTHPRIV if it
doesn't exist.  Because it is intended for logging sensitive log messages, it
is better that a program trying to log such messages fail than that it log
them insecurely.

Initial patch by Federico Reghenzani.
