Title:
  5s boot delay added when System BootOrder not found

Status in shim package in Ubuntu:
  Fix Released

Bug description:
  # Overview
  Recent changes in boot logic moved grub from "removable disk" path to "/efi/ubuntu" in order to fix grub package updates. This had the side-effect of adding a 5-second boot delay in images. This was discovered in GCE images booting Bionic or newer, when vTPM is present.

  # Expected result
  The system to correctly boot from the first boot entry with no delay.

  # Actual result
  The system cannot find "System BootOrder", initializes defaults, and creates a 5-second delay in boot.

  # Steps to reproduce
  1. Launch any GCE bionic or newer image after 20210224
  2. View the serial console for the image and look for: "System BootOrder not found.  Initializing defaults." Afterward, there were are messages counting down, starting with "Booting in 5 seconds"
