nixos/installer/cd-dvd: use EFI/BOOT and EFI/BOOT/BOOT$ARCH.EFI rather than lowercase

Browse Source 
Reported in https://discourse.nixos.org/t/nix-iso-unable-to-boot-in-uefi-mode-but-other-distros-can/16473/24

There seems to be weird situations with casing and FAT8.3 filenames, UEFI firmwares and what not.
To increase our compatibility, let's ensure we have the critical stuff (the bootable) in uppercase.
