Mount /run/xtables.lock as FileOrCreate (#2841)

Otherwise, if the file doesn't already exist on the host at startup, it will be created as a directory. This breaks (among other things) `kube-proxy`, which leads to the AWS CNI not being able to reach the API-server, which leads to the node being stuck in `NotReady` state.
