David Yang 50d51cef55 selftests: forwarding: Reorder (ar)ping arguments to obey POSIX getopt
Quoted from musl wiki:

  GNU getopt permutes argv to pull options to the front, ahead of
  non-option arguments. musl and the POSIX standard getopt stop
  processing options at the first non-option argument with no
  permutation.

Thus these scripts stop working on musl since non-option arguments for
tools using getopt() (in this case, (ar)ping) do not always come last.
Fix it by reordering arguments.
