[LTP] Option '-n' is processing is missing

[Petr Vorel]

Hi Muthu,

> In the help, I am seeing the following option, but not processing in the main() function. -n Run LTP with network traffic in background.
Thanks for your bug report. Indeed, runltp script is missing -n option.
This is a result of 9519bb462 ("runltp: Remove references to netpipe.sh"), which
was fix of f7201dfc ("tools: Remove unused code.") and handled in #158 [1].
I'm going to fix it.

Kind regards,
Petr
