Current collective.xmltestreport recipe allows tests to see system site packages. This is often not desirable, since system syte-packages may conflict with app own dependencies. This makes collective.xmltestreport not really a zc.recipe.testrunner drop-in replacement, since zc.recipe.testrunner allows to exclude site packages from sys.path.
Basically, this patch unifies recipe.py with corresponding version from zc.recipe.testrunner.
