Dongsu Park bb699ff491 sys-kernel: remove blank kernel module nf-conntrack-ipv4 ...

So far Flatcar has kept a third-party patch to add a blank kernel
module `nf-conntrack-ipv4.ko` to avoid regression around Kubernetes.
The issue was that kube-proxy with ipvs started using `nf-conntrack.ko`,
which does not exist in Kernel < 4.19. The patch was originally added by
a24dbb6cb6.

However, Kubernetes 1.13 or newer already deals with the issue. It
automatically loads a different Kernel module according to Kernel
versions: `nf-conntrack-ipv4` for Kernel < 4.19, and `nf-conntrack`
for Kernel >= 4.19.
See 4b90559369 .

We can simply remove the Kernel module, as since then all production
systems have updated Kubernetes to the newer versions than 1.13.
