    website: Fix build when public dir is already populated
    
    All CGI scripts are set with 555 permission mode in the post-build
    target, and this makes the following builds hang if not cleaned the
    public (temp) directory before or changed CGI permissions to 755.
    
    Error: Error building site: process: readAndProcessContent: open
    /doc/website/public/cgi/mailindex.cgi: permission denied
