kernel.bbclass: Create relative symlinks from "zImage" to actual kernel image in...

* Make sure update-alternatives created relative symlinks in /boot (or whatever)
kernel image directory is used. This is required for tools like LAB (Linux As
Bootloader) which may mount rootfs over some other temporary fs tree to get access
to kernel to boot.
* Closes #1569.
