bitbake: compat/server/utils: Jettison pre python 2.7.3 workarounds

Now we've moved to require python 2.7.3, we can jettison the compatibility
workarounds/hacks for older python versions.

-# The xmlrpclib.Transport class has undergone various changes in Python 2.7
-# which break BitBake's XMLRPC implementation.
-# To work around this we subclass Transport and have a copy/paste of method
-# implementations from Python 2.6.6's xmlrpclib.

-# Upstream Python bug is #8194 (http://bugs.python.org/issue8194)
-# This bug is relevant for Python 2.7.0 and 2.7.1 but was fixed for
-# Python > 2.7.2
-#
-# To implement a simple form of client control, we use a special transport
-# that adds a HTTP header field ("Bitbake-token") to ensure that a server
-# can communicate with only a client at a given time (the client must use
-# the same token).
