  1. docs: improve override action documentation 

    Let's improve override action documentation and try to be precise
on security_ hooks overriding being possible starting from kernel
5.7

If some distro has backported the patch to allow fmod_ret override
on security_ hooks then all good, otherwise if it fails we are covered
by the documentation.

Also change the caution point to be more addressed to kernel developers
if they want to leverage tetragon kprobe capabilities and use error
injections, as they should get it right in the first place.
