Don't display invalid error message when socket in use

Previously, when the listening socket was already in use, this error message was displayed:

    ...
      File "/private/tmp/n/lib/python2.7/site-packages/Paste-1.7.5.1-py2.7.egg/paste/httpserver.py", line 1106, in server_close
        self.thread_pool.shutdown(60)
    AttributeError: 'WSGIThreadPoolServer' object has no attribute 'thread_pool'

We prevent this by checking if `self` has a `thread_pool` attribute before trying to reference it.

Fixes issue #5 (https://bitbucket.org/ianb/paste/issue/5/invalid-error-message-when-the-socket-is)
