🐛 [shell.py] Fix ssh.copy() into Windows boxes

With consistent=True (default), copying over the same file on a
Windows machine would fail horrendously like:

```OSError('Failed to change the permissions and ownership of the
remote temporary path <FILE_NAME>.<SOME_UUID>.tmp: Failure')```

We couldn't care less about that behavior on those machines, we just
want overwrites to work :)
