Red Hat does not provide kpatch-build in the kpatch package as we don't
support customers creating and running their own kpatches. For kpatch-patch
packages, we do manage the build requirements (including the gcc plugin on
ppc64le) in its own dist-git repo. @coxu found the issues/tickets where we
noted as much in the upstream project README.md. So tl/dr; kpatch is OK with
removing this as a _kernel_ build requirement.
