Subject: [PATCH net-next 1/4] selftests: drv-net: force pseudo-terminal allocation in ssh

This is not yet needed, because we don't terminate remote background
commands. But once we do, if we run ssh without -t the ssh session
may close and the program may carry on happily running.

I have hit this problem experimenting with mausezahn, let's fix
it already to avoid someone else wasting time debugging it.
