Actually, kern/efi/init.c:grub_efi_set_prefix does not use the "user defined"
grub_prefix at all.

Currently, it gets the device path of the grub.efi binary, and traverses to
there. So, it only works when the modules are in the same directory as
grub.efi itself.

On the other hand, as the path is extracted using EFI's API (IIRC), it sounds
like an EFI bug that it mises up case like this. So the FAT case sensitivity
patch is then inevitable ...
