Patch addressing the issue

Description of problem:
jabberpy library (and by extension osad / osa-dispatcher) are not IPv6
ready. The library simply assumes all connections to jabber server are
plan IPv4.

Version-Release number of selected component (if applicable):
jabberpy-0.5-0.20

How reproducible:
Always

Steps to Reproduce:
1. Install Satellite 5.4.1 in an IPv6 only environment
2. Make sure jabberd services are listening on IPv6 addresses (but #715299)
3. Check osa-dispatcher startup.
  
Actual results:
osa-dispatcher won't start, following error is present in osa-dispatcher.log:

Traceback (most recent call last):
  File "/usr/share/rhn/osad/jabber_lib.py", line 254, in setup_connection
    c = self._get_jabber_client(js)
  File "/usr/share/rhn/osad/jabber_lib.py", line 311, in _get_jabber_client
    c.connect()
  File "/usr/share/rhn/osad/jabber_lib.py", line 577, in connect
    jabber.Client.connect(self)
  File "/usr/lib/python2.6/site-packages/jabber/xmlstream.py", line 464, in connect
    else: self._sock.connect((self._hostIP, self._port))
  File "<string>", line 1, in connect
gaierror: [Errno -2] Name or service not known

Expected results:
osa-dispatcher starts all right.

Additional info:
Required for a successful IPv6 Satellite deployment.
