Fixed Cisco ASA firewalls patterns for outbound and inbound directions

There is a problem with the built-in patterns for Cisco ASA firewalls. When the direction is "outbound", the src_ip/src_port and dst_ip/dst_port are reversed. This PR fixes this.
The Logstash Cookbook should be updated for this purpose, see #1369.

302013, 302014, 302015, and 302016 were correct as-is because the Built Teardown messages for TCP are always SRC/DST.
