Commit62089b8048("kbuild: rpm-pkg: Generate debuginfo package manually") effectively reverted commita7c699d090("kbuild: rpm-pkg: build a debuginfo RPM") but the approach it took is not safe for older RPM releases. Restore commita7c699d090("kbuild: rpm-pkg: build a debuginfo RPM") for the !CONFIG_MODULE_SIG case to allow more environments and configurations to take advantage of the separate debug information package process.
