Bug description:
  systemd-stub fails to boot when loaded via peimage.

  This is because peimage internally allocates an ImageHandle for images
  it starts and loads. systemd-stub  will then pass its own ImageHandle
  as ParentImageHandle to the firmware's LoadImage() function to load
  and start the embedded Linux kernel.

  The UEFI spec doesn't elaborate on this being allowed or not, but it
  seems like edk2 based firmwares try to locate private data attached to
  such a ParentImageHandle, then assert.
