Comment 12 for bug 1576066

So to summarize: in zesty, artful `scmp_sys_resolver -a x86 socket` will return: `-101`. The syscalls are still there in the kernel and libc its just that libseccomp reports a pseudo number again (which it did not in xenial).

The reason why we are seeing negative syscall numbers from libseccomp again is: https://github.com/seccomp/libseccomp/commit/73d83e45efbe8c31067c97155162f17ca51b7435

The interessting question is what we should do - the most simple answer is to just revert this, this would be consistent with xenial. But given that its an upstream commit I'm hesitant to do this.
