[Buildroot] [PATCH 1/1] grub-efi: align the rootfs to start at 16MB offset from start of the image

[Florian La Roche]

For grub-efi we can align the rootfs to start at exactly 16MB from the
beginning of the disk. This can be done by reducing the vfat partition
to be 32 KB smaller than its 16MB size, just like the offset of the vfat
partition.
