ensure modules_sign runs even if debuginfo is not produced

tested most of the possible with_* options... hopefully i didn't
miss anything.

+- Ensure modules are signed even if *-debuginfo rpms are not produced by
+  re-defining __spec_install_post and adding a hook after all strip
+  invocations. Ideally, in the future, we could patch the rpm macro and
+  remove the re-define from kernel.spec, but that's another windmill to tilt
+  at.
