io/console: unknown key code for names with nul

* ext/io/console/console.c (console_key_pressed_p): raise the same
  exception, "unknown virtual key code", for names with nul chars.
  though console_win32_vk() considers the length and can deal with
  nul chars, rb_sprintf() raised at PRIsVALUE previously, so quote
  it if it is unprintable.
