Use passive mode for the data connection. Passive is the internal default
behavior, but using this option can be used to override a previous --ftp-port
option.

If this option is used several times, only the first one is used. Undoing an
enforced passive really isn't doable but you must then instead enforce the
correct --ftp-port again.

Passive mode means that curl will try the EPSV command first and then PASV,
unless --disable-epsv is used.
