The size estimate was counting the /EFI/BOOT/ contents twice and then
doubling that. Only count things once, then double it for the
System/Library/CoreServices/ copy.
hard-links don't work. With CoreServices hardlinked to /EFI/BOOT/ the
Mac won't boot. With /EFI/BOOT/ hardlinked to CoreServices grub2 cannot
read the config file so there are 2 real copies.
This reduces the image size from 21M to about 12M
The aarch64 change to use shim (6907567) also stopped using mixed-case
names for BOOT${efiarch}.efi (so it's always .EFI and ${efiarch} is X64
IA32 AA64 etc. now), and mkefiboot needs to match that.

There's a small amount of additional metadata required for the Mac boot
images to appear as bootable devices in the startup preferencs, so add
support for generating that.

This adds the new "mkefiboot" cmd, which creates an efiboot img in the
magical way that EFI requires. There doesn't seem to be a good tool for
this (unlike the existing tools for all the other weirdo boot image
types) so it was necessary to create one.
