krops: add allocateTTY to writeDeploy

With allocateTTY, nixos-rebuild runs with a terminal, so it shows colours
and progress: on remote targets, ssh gets -t, which allocates a terminal
if its own input is one, and on the local target, expect's unbuffer
provides one.

The nixos-rebuild stand-in records whether its output is a terminal.
