Subject: [PATCH 0/2] kbuild: rpm-pkg: Address -debuginfo build regression
 with RPM < 4.20.0

Steve reported a build issue with commit 62089b804895 ("kbuild: rpm-pkg:
Generate debuginfo package manually") on RHEL9, which has an older
version of RPM than what I tested. Turns out that RPM 4.20.0 fixed an
issue with specifying %files for a -debuginfo subpackage.

The first patch restricts the new -debuginfo package generation process
to CONFIG_MODULE_SIG=y and RPM >= 4.20.0 to ensure it is actually
necessary and working. The second patch restores the original -debuginfo
package generation process from commit a7c699d090a1 ("kbuild: rpm-pkg:
build a debuginfo RPM") when CONFIG_MODULE_SIG is disabled to keep the
-debuginfo package around for older versions of RPM.
