[PATCH v3 1/5] conf/image-uefi: fix building images for multilib case

[dbaryshkov@gmail.com]

From: Dmitry Eremin-Solenikov <dmitry_eremin-solenikov@mentor.com>

Building live images for lib32-core-minimal-image will fail because
image target override won't match grub's override. Fix this by
introducing anonymous python function. A proper fix should be to
introduce multilib overrides, but it will be more intrusive.
