* src/ftp.c (getftp): Do not use PORT when PASV fails.

Fix IP address exposure when automatically falling back from
passive mode to active mode (using the PORT command). A behavior that
may be used to expose a client's privacy even when using a proxy.
- FTPServer.pm's handling of TYPE command would ignore binary mode
transfer request.
- The FTP server would run into dead loop sending the same content
forever.
