DLPX-94112 Additional EFI and systemd-boot packages

[tonynguien]

Background

Adding the systemd-boot and EFI related packages necessary for creating an EFI boot image.

PR delphix/appliance-build#792 is the follow on change which will generate EFI boot image.

Testing Done

Making sure current BIOS image build is still functional and EFI build would also work.

delphix-platform build - https://ops-jenkins.eng-tools-prd.aws.delphixcloud.com/job/linux-pkg/job/os-upgrade/job/build-package/job/delphix-platform/job/pre-push/
combine-packages - https://ops-jenkins.eng-tools-prd.aws.delphixcloud.com/job/linux-pkg/job/os-upgrade/job/combine-packages/job/pre-push/143/

Then appliance builds with current BIOS and EFI changes to build artifacts. Below are outputs from BIOS and EFI engines.

@tonynguien which of these packages are required to build the relevant packages, and which ones are required to be installed at runtime? The build dependencies should not be present on Delphix Engines (on variants that ship to customers), but only on the build environments where we do builds with linux-pkg and/or appliance-build.

OK. I'm not clear on the distinctions for builds and runtime requirements.

grub-efi-amd64-bin, systemd-boot, and efibootmgr should be installed at runtime. efitools is used to work with EFI and Secure Boot variables so it should be needed at runtime.

dosfstools provides the mkfs.fat which we need at image creation though probably not strictly at runtime since I believe we can mount fat fs without dosfstools
