Fix the AuditFork() to prevent the loss of STDERR. Turns out
(something I just managed to remember) is that if you call the shell without STDERR=2, then the shell has no place to send STDERR. The only way to get this correct is to use POSIX::dup2 instead of the standard perl open function. Well, I bet there is a way (or 10 ways) to do this, but this is one that stumbled onto. libaudit does a lot of descriptor messing around. BTW; this is also why we sometimes lose STDERR from the XMLRPC server.
