kernel: introduce use/kernel/latest

Kernel flavours differ on secondary arches (and there's a bunch of platform-specific kernels for ARM systems), so let's provide some more flexible scheme than hardwiring un-def into images. This might be further enhanced to e.g. set KFLAVOURS to $$(KFLAVOURS_LATEST)) with it being preset to un-def where available so rpi images could set it to rpi-un, and still get reasonable starterkits for free. The corresponding commit in RELENG-e2k-p9-starterkits private branch just tore un-def apart => unmergeable.
