maintainers: Add myself and Kevin Zhao as ARM64 maintainers

As we've enabled the k8s tests for ARM64, please, let's have us as
maintainers.  The main maintainer will be Kevin, and I may even be able
to be dropped from the list in the near future, but ... at least for now
... let's keep both of us there.
