bootloader: fix arm64 install path

Browse Source 
This fixes a regression introduced by
Ia99687815667c3cf5e82cf21d841d3b1008b8fa9

It turns out that [[ -d /usr/lib/grub/*-efi ]] is not a good check,
because [[ doesn't split that and try to glob match ( [ would ).  This
has resulted in us triggering this path on ARM64.

This is an x86-64 only check, because on other platforms we either
don't support EFI or are EFI only.  Restrict this check to get arm64
working again.
