Ensure GRUB_KERNEL_MACHINE_DATA_END is always consistent with the
        rest of GRUB, and breakage doesn't happen if its value were modified.

        * include/grub/i386/pc/kernel.h (GRUB_KERNEL_MACHINE_RAW_SIZE):
        Redefine as an offset from `GRUB_KERNEL_MACHINE_DATA_END' instead of
        a constant (same value).
        * kern/i386/pc/startup.S: Replace hardcoded `0x50' with
        `GRUB_KERNEL_MACHINE_DATA_END' (same value).
