While working on https://github.com/python/cpython/pull/28060 we've noticed that `test.test_tools.test_md5sum.MD5SumTests.test_checksum_fodder` fails on Windows:

```
======================================================================
FAIL: test_checksum_fodder (test.test_tools.test_md5sum.MD5SumTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "D:\a\cpython\cpython\lib\test\test_tools\test_md5sum.py", line 41, in test_checksum_fodder
    self.assertIn(part.encode(), out)
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AssertionError: b'@test_1772_tmp\xc3\xa6' not found in b'd38dae2eb1ab346a292ef6850f9e1a0d @test_1772_tmp\xe6\\md5sum.fodder\r\n'
```

For now it is ignored.
