fix(nix/runTestsuite): use s6-portable-utils r/2336

Same as 221698c603dcb318c609b4d21cb2a9fada44a14c

We had a bunch of instances of
https://github.com/NixOS/nix/issues/2176,
where nix would exit with a “killed by signal 9” error.

According to Eelco in that issue, this is perfectly normal behaviour
of course, and appears if the last command in a loop closes `stdout`
or `stdin`, then the builder will SIGKILL it immediately. This is of
course also a perfectly fine error message for that case.

It turns out that mainly GNU coreutils exhibit this behaviour …

Let’s see if using a more sane tool suite fixes that.
