This was a bit tricky: We start the ssh binary, but we want it to ignore SIGINT. In contrast, restic itself should process SIGINT and clean up properly. Before, we used `setsid()` to give the ssh process its own process group, but that means it cannot prompt the user for a password because the tty is gone. So, now we're passing in two functions that ignore SIGINT just before the ssh process is started and re-install it after start.
