FS resource name contains the mounted dir "hostfs"

[uri-weisman]

Describe the bug

This is not a degradation. Cloudbeat sends the FS resource path including the mounted directory /hostfs . The value should be the FS path on the host, not the path from the cloudbeat container.

hostfs/var/lib/kubelet/kubeconfig => var/lib/kubelet/kubeconfig

Preconditions Environment: https://staging.elastic.co/8.6.0-94db6bc6/summary-8.6.0.html
