Update the yaml files.

Describe the bug
https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.16.md#deprecations-and-removals
we have to use apps/v1 places like here
https://github.com/falcosecurity/falco/blob/dev/integrations/k8s-using-daemonset/k8s-with-rbac/falco-daemonset-configmap.yaml#L1

How to reproduce it

1. use latest k8s
2. apply the yaml files

You will get below error
kubectl apply -f k8s-with-rbac/falco-daemonset-configmap.yaml
error: unable to recognize "k8s-with-rbac/falco-daemonset-configmap.yaml": no matches for kind "DaemonSet" in version "extensions/v1beta1"
