archive: document that --add-virtual-file takes full path

Tom Scogland noticed that `--add-virtual-file` option uses the path specified as its value as-is, without prepending any value given to the `--prefix` option like `--add-file` does. The behaviour has always been that way since the option was introduced, but the documentation has always been wrong and said that it would use the value of `--prefix` just like `--add-file` does. We could modify the behaviour to make it literally work like the documentation said, but it would break existing scripts the users use.
