MAINTAINERS: hand over Kbuild maintenance

I'm stepping down as the maintainer of Kbuild/Kconfig.
It was enjoyable to refactor and improve the kernel build system,
but due to personal reasons, I believe it's difficult for me to
continue in this role any further.

I discussed this off-list with Nathan and Nicolas, and they have
kindly agreed to take over the maintenance of Kbuild with Odd Fixes.
I'm grateful to them for stepping in.

As for Kconfig, there are currently no designated reviewers, so the
maintainer position will remain vacant for now. I hope someone will
step up to take on the role.
