[OE-core] [PATCH] bootimg.bbclass: Tweak iso images to become hybrid images

[Richard Purdie]

From: Damien Lespiau <damien.lespiau at intel.com>

This allows iso images to be written to usb keys and booted on systems which
have a BIOS which support this. There is no real down side to tweaking the iso
images in this way.
