LOG: [lit] [test] Fix the shtest-readfile test on Python 3.13 on Windows (#160503)

Python 3.13 considers "/file/does/not/exist" to not be an absolute path
on Windows, so the test runner does os.path.join(cwd, filePath), which
can end up with an output path such as "D:/file/does/not/exist".

Accept a potential prefix before the missing path here.

This fixes running the lit tests on Windows with Python 3.13.
