Uncapitalize EFI to efi
Created by: leee
This patch uncapitalizes
efi - the Architect disk setup uses
/boot/efi, and so this inconsistency causes the installation of GRUB to break.
It is also okay to go the other way around - that is, the disk setup uses
/boot/EFI, but seeing as
/boot/efi is used in several other areas here, it is easiest to perform this 2 line change as opposed to many more.
Apologies for not being able to sign this patch - I am editing this on a machine with fresh M-A installation which provided me a half-broken GNOME (because of the
 issue with installing GNOME in the full variant) and spent too much time not understanding why that and GRUB was not installing properly until now.
