Bug description:
  [ Impact ]

   * Microsoft is rolling out SBAT revocations via Windows update such that
     single-boot machines with Windows won't be able to boot shim executables
     with SBAT level less than shim,4.

   * For the 22.04.5 media we would like to include the 15.8 shim so that
     it is bootable on such machines.

  [ Test Plan ]

   * Ensure that the resulting cd-boot images contain our 15.8-0ubuntu1 MS UEFI
     CA signed shim executable.

  [ Where problems could occur ]

   * Impact is limited to media built using the new cd-boot images which will go
     through the usual rigorous QA process.

   * The shim and grub that will be used as part of this process will be in the Jammy
     archive before being part of media.
