6c0e5297fa fix(integrations/k8s-using-daemonset): --cri flag correct socket path
The libsinsp cri interface prepends (at runtime) the `HOST_ROOT` prefix.

Thus, even if the CRI socket has been mounted on
`/host/var/run/containerd/containerd.sock`, the correct `--cri` flag
value is `/var/run/containerd/containerd.sock`.

Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Falco audits a system at the most fundamental level, the kernel. Falco then enriches this data with other input streams such as container runtime metrics, and Kubernetes metrics. Falco lets you continuously monitor and detect container, application, host, and network activity—all in one place—from one source of data, with one set of rules.

### Build & Testing Dockerfiles
- `./builder`: `falcosecurity/falco-builder` - The complete build tool chain for compiling Falco from source. See [the documentation](https://falco.org/docs/source/) for more details on building from source.
- `./tester`: `falcosecurity/falco-tester` - Container image for running the Falco test suite.
## Alpha Release Containers
These Dockerfiles (and resulting container images) are currently in `alpha`. We'd love for you to test these images and [report any feedback](https://github.com/falcosecurity/falco/issues/new/choose).
### Slim and Minimal Dockerfiles
The goal of these container images is to reduce the size of the underlying Falco container.
- `./slim-dev`: Like `./dev` above but removes build tools for older kernels.
- `./slim-stable`: Like `./stable` above but removes build tools for older kernels.
- `./minimal`: A minimal container image (~20mb), containing only the files required to run Falco.
### Init Containers
These container images allow for the delivery of the kernel module or eBPF probe either via HTTP or via a container image.
- `kernel/linuxkit`: Multistage Dockerfile to build a Falco kernel module for Linuxkit (Docker Desktop). Generates an alpine based container image with the kernel module, and `insmod` as the container `CMD`.
- `kernel/probeloader`: Multistage Dockerfile to build a Go based application to download (via HTTPS) and load a Falco kernel module. The resulting container image can be ran as an `initContainer` to load the Falco module before Falco starts.
> Note: `falco-builder`, `falco-tester` (and the `docker/local` image that it's built on the fly) are not integrated into the release process because they are development and CI tools that need to be manually pushed only when updated.
