datapath-windows: Conntrack - Enable FTP support

Enable the support for tracking FTP connections in the Connection tracker.
This checks an incoming ftp control connection to extract the related data
connection. When a matching data connection arrives, it would then update
the connection entry to point to the original control connection.
