The commands used were (roughly):

	hack/pin-dependency.sh github.com/opencontainers/runc v1.0.0
	hack/lint-dependencies.sh
	# Follow its recommendations.
	hack/pin-dependency.sh github.com/cilium/ebpf v0.6.1
	hack/pin-dependency.sh github.com/opencontainers/selinux v1.8.2
	hack/pin-dependency.sh github.com/sirupsen/logrus v1.8.1
	# Recheck.
	hack/lint-dependencies.sh
	GO111MODULE=on go mod edit -dropreplace github.com/willf/bitset
	hack/update-vendor.sh
	# Recheck.
	hack/lint-dependencies.sh
	hack/update-internal-modules.sh
	# Recheck.
	hack/lint-dependencies.sh
