stream.py: Don't use class decorators.

Commit 8cc820 (python/ovs/stream: teach stream.py tcp socket) made a
change that used class decorators.  Unfortunately, they were not
introduced until Python 2.6.  XenServer uses Python 2.4, so the change
caused some Python-based daemons not to start.  This commit uses an
alternate syntax suggested by Reid Price.

Bug #13580
