[PATCH] abort when core.img is too big

With the addition of memdisk, it is too easy for user to create an image
big enough that would corrupt upper memory (starting with vga region).  This
happens at roughly ~600 kiB memdisk size.

This patch adds a check in grub-mkimage to prevent this.  I did also take
the opportunity to reuse the upper memory macro to avoid hardcoding its
address for VGA stuff.
