This fixes XML unittest fallout from the #115398 security fix. When configured using --with-system-expat on systems with older pre 2.6.0 versions of libexpat, our unittests were failing.

  • sax|etree: Simplify Expat version guard where simplifiable

Idea by Matěj Cepl

  • sax|etree: Fix reparse deferral tests for vanilla Expat <2.6.0

This does not fix the case of distros with an older version of libexpat with the 2.6.0 feature backported as a security fix. (Ubuntu is a known example of this with its libexpat1 2.5.0-2ubunutu0.1 package)
(cherry picked from commit 9f74e86)
