Add UEFI Secure Boot packages to enable booting on systems
with Secure Boot enabled:
- shim-signed: Microsoft-signed shim bootloader
- grub-efi-amd64-signed: Signed GRUB EFI bootloader
- grub-efi-amd64-bin: GRUB EFI binaries
- efibootmgr: EFI boot manager utility
This is mandatory for modern UEFI systems that ship with
Secure Boot enabled by default.
Compliance: UEFI Secure Boot specification
