scripts: test null forwarding

This script ease testing of basic initializations and Rx/Tx bursts.
It may help to check obvious regressions.
In order to run it on a standard development machine, it doesn't use
neither hugepages nor real interfaces.

The optional parameters are:
- build directory (default: build)
- coremask (default: 3 i.e. cores 0 and 1)
