Change onvm-pktgen Submodule to Upstream Pktgen (#81)

The onvm-pktgen submodule was only adding an example lua config and a simplified `run-pktgen.sh` script. As there were no changes to actual pktgen code we have moved those scripts into `/tools/Pktgen/openNetVM-Scripts`. Because of this we no longer need to maintain our own `onvm-pktgen` repo, instead we can use upstream pktgen.

Commit Log:

* Changing pktgen submodule

* Fix run_pktgen.sh script

* Readme, script docs updates

* Fix pointer ot master branch
