    grub-efi.bbclass: Fix path in startup.nsh for iso image.
    
    The path in startup.nsh for iso image is corrupted as follows:
    fs0:\EFI\BOOT^Hootx64.efi
    
    Using printf will emit correct path which is:
    fs0:\EFI\BOOT\bootx64.efi
    
    This happens because of echo command. Switching to printf
    like the one used in efi_populate() function.
