[poky] [PATCH 2/2] bitbake/xmlrpc: only use BBTransport for affected Python versions

[Joshua Lock]

From: Joshua Lock <josh at linux.intel.com>

Upstream have fixed the xmlrpclip.Transport() bug from Python #8194 for
the Python 2.7.2 release, therefore as we know which versions of the
standard library are affected we can only use our copy/paste class when
it's needed.
