kubeadm/cilium: disable SELinux for Cilium

Once the daemon set is started with `unconfined_t` it does not work with
enforced SELinux because it hits a denial from transitioning to `kernel_t` to
`unconfined_t` (and this normal because currently everything runs with
`kernel_t` including container runtimes)

Can be dropped once it works fine with `spc_t` label with the SELinux
upgrade.
