runtests: set web.ipv6 if we use IPv6

As explained by the previous patch, we need to set "web.ipv6=True" if we
decide to use IPv6. Otherwise "hg serve" will still try to listen on IPv4.

This patch makes it so by appending web.ipv6 to "extra configs".

This patch was tested in a Linux system with IPv6, by the following steps:

  1. Change hgweb/server.py temporarily to write a file if
     IPv6HTTPServer.__init__ is called.
  2. run-tests.py -l --keep-tmpdir test-serve.t
  3. Check the generated .hgrc, make sure it sets web.ipv6=1.
  4. Check the log file to make sure IPv6HTTPServer.__init__ is called.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
