lib/host: Avoid using identical source and destination paths in execute_script scp

Using the same path for both source and destination may cause scp to fail,
especially when the source path (e.g. a temp path on macOS) does not exist
on the remote system. Thus, resorting to use `/tmp/` and random name from
`sctipt.name` on destination.
