When creating core.elf with SBAT the grub-mkimage does not check if an SBAT metadata file contains at least an SBAT header or not. It leads to adding an empty SBAT ELF note for PowerPC and the .sbat section for EFI. Fix this by checking the SBAT metadata file size against the SBAT header size before adding SBAT contents to the ELF note or .sbat section.
