[issue26468] shutil.copy2 raises OSError if filesystem doesn't support chmod

[Vojtěch Pachol]

New submission from Vojtěch Pachol:

`copy2` checks if `os` nodule has `chmod` and then it uses it without thinking. 

On filesystems that doesn't support `chmod` it ends with

    OSError: [Errno 95] Operation not supported: <filename>

which is not acceptable since documentation says "copy2() never returns failure".
