Log Message:
Add a new ptrace(2) ATF exploit for: CVE-2018-8897 (POP SS debug exception)

The original expolit and mitigation have been developed by Maxime Villard.

I've reworked the shared code and adapted for the ATF context.
I've included PIE-aware version (RIP/EIP relative) and introduced
additional comments to the explanation how to trigger the flaw.

This test passes on NetBSD/8.99.17.
