Hard coding port 8000 in package-tests.el causes the test to fail if
something is already listening on that port.  Change code so it uses
any available port.

* tests/lisp/emacs-lisp/package-tests.el
  (package-test-update-archives-async): Do not hard code port number
  and instead parse it from server’s standard output.

* tests/lisp/emacs-lisp/package-resources/package-test-server.py:
  Do not hard code port number.  Use any available one instead.

Note that currently argument parsing in package-test-server.py is
dysfunctional (passing an argument causes server_address to never be
set) so while my patch would fix that (by removing that unused feature).

(Sorry, I did not notice that you have write access.) Feel free to fix
that if it bothers you.
