This use case comes up with e.g. `--copy-ec /tmp`. The existing code will see that `/tmp` exists and has a different UID and hence will use `shutil.copy_file` which expects the target to not be a folder. It hence fails with "[Errno 21] Is a directory" Use `shutil.copy` as was likely intended anyway.
`shutil.copy` tries to change permissions which isn't allowed in the case where it is used. As we already made sure the target is a file we can use `shutil.copyfile`
