I think this is just a problem in listing_mode -- a script which accesses $arg1
on this probe still works fine. We list args using derived_probe::getargs(),
but the uprobe_derived_probe doesn't know about the SDT debuginfoless args.
This is only for x86, so we should treat it separately from this s390 issue.
