s390: Remove _dl_skip_args usage
Since ad43cac44a the generic code already shuffles the argv/envp/auxv on the stack to remove the ld.so own arguments and thus _dl_skip_args is always 0. So there is no need to adjust the argc or argv. Checked on s390x-linux-gnu and s390-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
