Pragmatic Software 03fb901291 pbot-vm: fix potential time-out when outputting 0 ...

If the output from a code snippet is `0` without a newline,
Perl treats this as a false value. When Guest::process_command()
returns a false value, that signals to guest-server::serial_server()
that it is the parent returning and so it will not send the result back
to the host.

However, `0\n` is a true value. Solution: always append a final newline to
the guest output.
