Update:
I downloaded the source code of the latest Gringotts from the developer's site and compiled it on my Hardy box. The same problem occurs: "Memory protection from ptrace spying" is marked with a red button, and overall security level is marked "low". There is no configure option to enable or disable this protection.
Therefore, I think we can say that this is an upstream issue.
