Add a kprobe verification functionality

[Adam-pi3]

Add a new logic to the integrity verification routine verifying if the kprobes are enabled and correctly run. This commit makes kprobe verification functionality as an independent module invoked by integrity verification routine as well as during initialization to make sure kprobes are enabled and run as intended (otherwise, initialization fails).

How Has This Been Tested?

I've done a few tests:

• Manually disable kprobes before initialization (new feature correctly detects kprobes don't work)
• There is no problem when kprobes are enabled (verified the code-flow and debug messages that feature works and run as intended)
• Manually disable kprobes after initialization (new feature correctly detects kprobes don't work)
• There is no problem when kprobes are enabled (verified the code-flow and debug messages that feature works and run as intended)

@Adam-pi3 Please squash the "Minor fix" commit into the previous one (I'd use the fixup keyword in interactive rebase to do this), and force-push.

Edit: Also, going forward let's be doing the force-pushes right away, instead of letting temporary commits accumulate in PRs and then needing to be squashed as a separate step. GitHub allows for easy review of changes between force-pushes.

Overall, I think this is almost ready for merging. Thank you, @Adam-pi3!
