David Yang a4a6e1c878 selftests: forwarding: Reorder (ar)ping arguments to obey POSIX getopt 
[ Upstream commit 50d51cef55 ]

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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
