The debug scripts cgiwrapd and nph-cgiwrapd give away much information
about the CGI environment.
Fix: Installs cgiwrapd/nph-cgiwrapd as a separate binary and removes suid
and execute permissions. A note is added to pkg-message explaining
how to enable cgiwrapd/nph-cgiwrapd.
This fix was suggested by Neil Darlow <email@example.com>.
