Subject: Fix port allocation in tests

 For some reason, when running the test suite under sbuild, several tests crash
 with an error of `Errno::EADDRINUSE: Address already in use - listen(2)`. The
 tests just work when building outside of sbuild.

 Somehow, passing :Port => 0 seems to be making WEBrick allocate the same port
 over and over. I couldn't reproduce this interactively.

 This patch fixes the issue by assigning explict port numbers to servers and
 proxy servers created in the test suite, and is most probably Debian-specific.
