docs: retain cilium autoMount pending upstream hostPath fix

Partial rollback of 76fa45a.

The cilium helm chart requires an fix to handle the hostPath
at /sys/fs/bpf when bpf.autoMount.enabled=false. The earlier commit
disabled bpf automount, removing the init container's mount. Helm
missed adding the hostPath, and neither /sys nor /sys/fs got added.
This made cilium wrongly mount /sys/fs/bpf.

Fixes error message at: #7565 (comment)
