Subject: [PATCH] Add kmod.attr from redhat-rpm-config

This file is currently shipped via the binary redhat-rpm-config package
itself, so we need an explicit Conflicts to avoid broken upgrades, as
well as actually remove the file from the next redhat-rpm-config build,
which we'll also do via #1959924.
