If you add "open", there is a chance you also want to block "openat"...

So make this easy by allow adding system call by group names to the policy.

Also, maybe take some inspiration from pledge().

If there was a kernel update, but no qssb.h update or code is using an outdated verison, new syscalls could have been added that are not in any group yet.

Thus, we may habe to auto blacklist all those that we do not know.

Alternatively, adding syscalls by groups should only be allowed for whitelisting?
