wsgi unit tests require binding to port 4444

[Eric Harney]

Unit tests for wsgi fail if port 4444 is used by another process. The test trying to use port 4444 (test_server_pool_waitall) does not require a specific port, so letting it choose an unused port via port 0 would be ideal.

    Tests: Don't require binding to port 4444

    If some other process is listening on port 4444,
    test_server_pool_waitall will fail with:

    error: [Errno 98] Address already in use

    This test doesn't require use of this specific port,
    so let it pick an unused port to avoid this failure.

    Closes-Bug: #1421759
