samples/pktgen: Add sample scripts for pktgen facility
These are Robert Olsson's samples which used to be available from <ftp://robur.slu.se/pub/Linux/net-development/pktgen-testing/examples/> but currently are not. Change the documentation to refer to these consistently as 'sample scripts', matching the directory name used here.
