linux: add option to explicitly specify the kernel image name

Browse Source 
For example the upcoming qemu-xtensa patch is using this feature,
where the target is called "zImage", but the resulting kernel name
is "Image.elf".

The filename of the kernel image, if it is different from the
make target (above). Only Xtensa uses a filename different from
the make target. Defaults to BR2_LINUX_KERNEL_IMAGE_TARGET_NAME.
If unsure, leave it empty.
