[issue1200] grml-debootstrap: password prompt doesn't work through ssh

verified. you can reproduce this with this simple script:

--<--
#!/bin/sh

askpass() {
  # read -s emulation for dash. result is in $resp.
  set -o noglob
  stty -echo
  read resp
  stty echo
  set +o noglob
}

echo -n "Enter new Windows password for user root: "
askpass
echo
echo "You entered $resp"
-->--

The problem is that calling ssh foo at bar cmd won't allocate a TTY and calling stty without a TTY is 
kinda... stupid.

You can workaround this by calling ssh -t foo at bar cmd.

Not sure how we would fix that properly. Not calling stty in the case there is no TTY would reveal 
your password (try `ssh ... passwd`). We could check for a TTY and error out early.
