Trying if this would do the trick; conditionally add the new syscalls based on kernel version (not sure if it works though)

OK, looks like this won't fix the issue. I was hoping that making these conditional would exclude them from the seccomp-profile, and make use of the stubs that runc creates, but that's not the case;

Yeah, this was a bit too naive of course; I thought "let's try change the default", but that means missing syscalls (not defined in the profile) will probably get ENOSYS as well;
