Fixed python2.6 compat for RFCSysLogHandler

(From the original bug report):
Currently used pattern in RFCSysLogHandler will fail for Python
2.6.x (using super(RFCSysLogHandler, self)).
In order to fix the broken Python 2.6.x compatibility, old style
explicit superclass method calls should be used instead.

Uses e.g. logging.handlers.SysLogHandler.__init__(self,...)
rather than super(RFCSysLogHandler, self).__init__(...)
