Work together with Emanuele Rocca during MiniDebCamp Hamburg 2024
* rebuild: New command line option: --architecture
* installer: Enable the GTK installer
* bootloader: Set a default bootloader
* no qemu-binary in chroot
When grub-efi-amd64-signed and grub-common have mismatched
dependencies (e.g. due to binNMUs), allow a shim-only secure boot.
The user has to enroll the hash of the EFI/boot/grub*.efi file and then
secure booting can continue.
Shim-only is supported only for '--uefi-secure-boot=auto'
This fixes the last non-reproducible file for KDE (bookworm):
* install-info has an unstable sort when a new section is started
Newer versions (not yet released) have been fixed
* The backup file (dir.old) does not need to be in the live image
