zmq-source: change the way how zmq-source handle the connection creation

 * In the source case syslog-ng use pull socket. When you use pull socket you must connect to socket instead of bind and the other part has to bind.
 * E.g.: pull -> connect | push -> bind
 * Remove the lot of c test scripts and use python instead.
