Bug description:
  Split out of bug 1894217.

  We're seeing a situation where curtin fails when the variable
  BootCurrent references does not exist.

  At boot, efibootmgr -v shows:

  BootCurrent: 0003
  Timeout: 10 seconds
  BootOrder: 0003,0004,0005,0006,0001

  Note that there are actually no individual boot entries in this
  output. BootCurrent and BootOrder are referencing Boot entries that do
  not apepar to exist.

  Later, curtin tries to set a new BootOrder that places the value of
  BootCurrent at the front. This causes efibootmgr to error out,
  apparently escalating to an installation failure:

          UEFI efibootmgr output after install:
          {'current': '0003', 'timeout': '10 seconds', 'order': ['0000'], 'entries': {'0000': {'name

  untu\\shimx64.efi)'}}}
          Setting currently booted 0003 as the first UEFI loader.
