Remove unnecessary calls to normpath().
Patch by: Jon foster <jon.foster@cabot.co.uk>
SymbolTransform.transform() is called a lot - more than 40 million
times in my "medium" test case[1]. os.path.normpath() does a fair
amount of work, so we should avoid calling it unnecessarily in
SymbolTransform.transform().
[1] My test case is a subset of the real conversion I'm doing, this
isn't an artificial stress test.
