Re: [PATCH net-next v3] 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.
