GetFileType is meant to return the type of the given file by using os.Stat. However, os.Stat doesn't work on Windows for Unix Sockets, causing an error to occur: [2-Socket Test] unexpected error : CreateFile C:\Users\Administrator\AppData\Local\Temp\test-get-filetype-2776877299\mt.sock: The file cannot be accessed by the system. This is a known issue and we're already using a workaround for this in pkg/kubelet/util/util_windows.go. This commit fixes this issue for GetFileType on Windows.
