Remove lockc-runc-wrapper, use fanotify

Monitoring runc processes can be done with fanotify in a similar way how inspector-gadget is doing that:

https://github.com/kinvolk/inspektor-gadget/blob/main/pkg/runcfanotify/runcfanotify.go

That will allow us to remove lockc-runc-wrapper and any necessity of configuring containerd or docker daemon to integrate with lockc. Everything will be possible to be done in lockcd.
