Log:
  boot1.efifat: provide a fallback startup.nsh
  
  In case the firmware falls through to executing startup.sh, populate it
  with the name of our boot loader. In normal operation this should not be
  necessary but may allow the system to boot if it would otherwise just
  remain at a shell prompt.
