iso: switch UEFI bootmode from systemd-boot to GRUB

Browse source 
systemd-boot can only read the ESP it launched from, so mkarchiso copies
vmlinuz + initramfs into efiboot.img on top of the ISO9660 copy (~244 MiB
duplicate). uefi.grub reads ISO9660 directly; iso/grub configs were already
present and BOS-branded.
