Makefile, conf, passt: Drop passt4netns references, explicit argc check

Browse source 
Nobody currently calls this as passt4netns, that was the name I used
before 'pasta', drop any reference before it's too late.

While at it, explicitly check that argc is bigger than or equal to
one, just as a defensive measure: argv[0] being NULL is not an issue
anyway.
