[OE-core] [PATCH] meta: classes: Add building dir to uImage creation

[Mylène Josserand]

On the do_uboot_mkimage task from kernel-uimage.bbclass, in case
KEEPUIMAGE is different than the default "yes" value, the uboot-mkimage
command fails because the path of the created uImage does not exist.

On this task, we are under the BUILDDIR so there is no folder arch/<ARCH>/boot.
Add the ${B} (for kernel build directory) as prefix to this folder fixes the problem.
