iptraf-ng: init at 1.1.4

This commit adds `iptraf-ng` which is a fork of `iptraf`. The original
has not been updated in ~10 years. This fork is more modern but
development is a bit slow (last update to master 15 months ago).
Nevertheless, unlike `iptraf` this one doesn't barf around and works
properly.

+      IPTraf-ng is a console-based network monitoring utility. IPTraf-ng
+      gathers data like TCP connection packet and byte counts, interface
+      statistics and activity indicators, TCP/UDP traffic breakdowns, and LAN
+      station packet and byte counts. IPTraf-ng features include an IP traffic
+      monitor which shows TCP flag information, packet and byte counts, ICMP
+      details, OSPF packet types, and oversized IP packet warnings; interface
+      statistics showing IP, TCP, UDP, ICMP, non-IP and other IP packet counts,
+      IP checksum errors, interface activity and packet size counts; a TCP and
+      UDP service monitor showing counts of incoming and outgoing packets for
+      common TCP and UDP application ports, a LAN statistics module that
+      discovers active hosts and displays statistics about their activity; TCP,
+      UDP and other protocol display filters so you can view just the traffic
+      you want; logging; support for Ethernet, FDDI, ISDN, SLIP, PPP, and
+      loopback interfaces; and utilization of the built-in raw socket interface
+      of the Linux kernel, so it can be used on a wide variety of supported
+      network cards.
