kernel/linux-kernel-base: Fix kernel build artefact determinism issues
With the 6.1 kernel we've seen reproducibility/determinism issues where the kernel
seems to rebuild headers referencing the hostname or local user. kernel-devsrc
building after the kernel seemed to trigger it in some cases.
Moving the definitions to the bbclass used by all the kernel recipe code including
kernel-devsrc seems to be the best way to ensure this doesn't happen.
