trafgen: Don't duplicate copyright/bug report/license string

Move the copyright/bug report/license string to an own constant and use
it for the output of help() and version() to avoid duplication and
prevent the strings from getting out of sync. This makes the text
section of trafgen.o slightly smaller:

before:
   text	   data	    bss	    dec	    hex	filename
  18512	      0	    104	  18616	   48b8	trafgen/trafgen.o

after:
   text	   data	    bss	    dec	    hex	filename
  18240	      0	    104	  18344	   47a8	trafgen/trafgen.o
