[spp] [PATCH] tools/sppc: add launcher for suricata

[yasufum.o at gmail.com]

From: Yasufumi Ogawa <yasufum.o at gmail.com>

This update is add launcher script for suricata. Here is an example of
usage. Suricata is expected from command line, so this launcher is jsut
to start bash and you need to suricata itself from bash. You notice that
you need to upload your suricata config before run launcher.

  $ docker cp your.cnf CONTAINER_ID:/path/to/conf/your.conf
  $ ./suricata.py -d 1,2 -fg -ci sppc/suricata-ubuntu2:latest
  # suricata --dpdk=/path/to/config
