clone: fall back to copying when linking does not work We use heuristics to make a decent guess at when we can save time and space by linking object files during a clone. Unfortunately checking the device id isn't enough, as those would be the same during e.g. a bind-mount, but the OS still does not allow us to link between mounts of the same filesystem. If we fail to perform the links, fall back to copying the contents into a new file as a last attempt.
