Commita7c699d090("kbuild: rpm-pkg: build a debuginfo RPM") adjusted the __spec_install_post macro to include __os_install_post, which runs brp-strip. This ends up stripping module signatures, breaking loading modules with lockdown enabled. Undo most of the changes of the aforementioned debuginfo patch and mirror commit16c36f8864("kbuild: deb-pkg: use build ID instead of debug link for dbg package") in kernel.spec to generate a functionally equivalent debuginfo package while avoiding touching the modules after they have already been signed during modules_install.
