Mantic minimal cloud images (ubuntu-cpc project) arm64 efibootmgr removal

[Philip Roche]

With the migration from linux-kvm to linux-virtual/genreic for the mantic minimal images we can now start building arm64 minimal cloud images.

When building initial test images we noticed that when comparing the amd64 minimized images and the arm64 images that the efibootmgr package was not installed in the arm64 images.

This is because for amd64 it is installed as a recommends of shim-signed but for arm64 we are installing shim-signed `--no-install-recommends`.

See https://git.launchpad.net/livecd-rootfs/tree/live-build/ubuntu-cpc/hooks.d/base/disk-image-uefi.binary#n115

This bug is to track the alignment of amd64 and arm64 when installing shim-signed and grub related packages.

In general for minimized images we should not be install recommends and for
non minimized we should. This policy should be aligned for all architectures.

Proposed MP https://code.launchpad.net/~philroche/livecd-rootfs/+git/livecd-rootfs/+merge/451891 to address this bug

[Steve Langasek (vorlon)]

Have questioned this approach on the MP. I think this should be reconciled in the other direction instead (don't install bootloader recommends, we shouldn't care about efibootmgr preinstalled in minimal images)

MP now superseded by https://code.launchpad.net/~philroche/livecd-rootfs/+git/livecd-rootfs/+merge/452152

I have tested amd64 and arm64 minimized and non minimized images successfully with these changes and confirmed boot works and secureboot still works too.

This bug was fixed in the package livecd-rootfs - 23.10.47
