wic: isoimage-isohybrid: fix UEFI spec breakage

It's really good that OE supports multiple EFI_PROVIDERs and that
commit 9a1709278de87 ("wic: isoimage-isohybrid: use grub-efi from
deploy dir") makes re-use of the grub-efi built image, but we should
still respect the standard otherwise the ISO will not boot, so install
grub images as boot[x64|ia32].efi not ${PN}-boot[x64|ia32].efi.
