feat(kernel): add hand-curated changelog entry

[dmcilvaney]

rpmautospec can't generate changelog entries for the kernel package since its too complex. Until we can find a solution to this issue we will maintain a manual changelog entry for each lock-fingerprint change.

Pull request overview

This PR introduces a hand-curated changelog mechanism for the kernel component to avoid relying on rpmautospec for changelog generation, which is described as impractical for the kernel spec’s complexity.

Changes:

• Bump azl_pkgrelease from 3 → 4 (component define + rendered macros), updating the kernel release.
• Add a spec-prepend-lines overlay to inject AZL-maintained %changelog entries at the top of the rendered kernel spec.
• Update the kernel lock input-fingerprint to reflect the component/config change.
