this is fragile, slow as fuck, breaks constantly under high concurrency,
and completely unnecessary since ssh bypasses the stdio file descriptors
*anyway*. we do still check that we see ssh messages to ensure that none
of our subprocess handling messes with ssh's /dev/tty, but that's it now

4b128008c5d9fde881ce1b0a25e60ae0415a14d5 in nixpkgs introduced a default
hashedPasswordFile for root in NixOS tests, which takes precedence over
the password option set in the nix-copy test.

without these changes the tests will very repeatably (although not very
reliably) wedge in our runs. the ssh command starts, opens a sessions,
does something, the session closes again, but the test does not move on.
adding *just* the redirect and not the unit waits is not sufficient
either, it needs both. this feels like a bug in the nixos testing
framework somewhere, but digging that far is not in the cards right now.
