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.

This is done via the /proc interface, and most easily done via pgset in

the scripts.
