e48b1eb9 - gh-89760: Fix os.path.realpath() for volume GUID paths on Windows (GH-155396)

gh-89760: Fix os.path.realpath() for volume GUID paths on Windows (GH-155396) The \\?\ prefix was stripped from the resolved path if it could not be resolved without the prefix and failed with the same error as the original path. This produced an invalid, seemingly relative path for a junction which points to a volume without a drive letter. The prefix is now only stripped for drive-letter and UNC paths.
