In order to add kubernetes 1.21.8 we need to add support for
golang 1.16.12. We're going to be removing kubernetes 1.21.3 so
we no longer need golang 1.16.6.
The ppc64le-vdso-fix.patch patch was merged upstream and so is
no longer applicable.
No direct testing is possible, but it is tested indirectly by
building and testing Kubernetes 1.21.8.
