[Mimedefang] syslog fix for embedded multiplexor.

[Lucas Albers]

Was this openlog/syslog multiplexor fix included in mimedefang 2.41?

> The problem:  The MIMEDefang multiplexor uses the openlog and syslog
functions to write to the syslog.  These functions use a file descriptor
kept in a static variable somewhere to do the actual writing.  However,
when the multiplexor forks off a child, the child closes all open FDs.
If the Perl filter then opens a file, it may happen to get the same FD
that the openlog/syslog functions expect to use.  Bad things ensue.  (On
my system, the FD conflict was causing slave processes to hang.)
