I'm starting to stumble my way through building an install image for
aarch64, and I changed gnu/system/install.scm to use 'grub-efi' in place
of 'grub' in the list of packages (~line 333). Grub-efi builds
successfully on armhf and aarch64 and grub does not, and as part of
compiling install.scm grub is built as part of assembling the image.

guix size grub:     157.5 MiB
guix size grub-efi: 160.5 MiB

I don't know a lot of how the install image is put together, or if using
grub-efi in place of grub for building the image would be a problem for
non-efi machines, but for non-intel machines at least we should use
grub-efi for the grub calls.
