Fixes [YOCTO #1951] The do_bootimg code can generate hybrid efi+pcbios images (syslinux and grub-efi) to boot on platforms with both EFI and legacy BIOS options. The current implementation copies the kernel, initrd, and rootfs twice, unnecessarily bloating the image size. This is an especially egregious bug on -sato images. Update the classes to use a common install of the kernel, initrd, and rootfs to the root of the boot media. Grub-efi, syslinux, and isolinux can all reference this location explicitly with a leading slash. Tested with an EFI+PCBIOS image in both EFI and PCBIOS boot modes on two platforms. No ISO image testing was performed.
