tools headers UAPI: sync arch/s390/kernel/syscalls/syscall.tbl with kernel

JIRA: https://issues.redhat.com/browse/RHEL-29796
Upstream Status: RHEL only

description
===========
Upstream, when there is a change in a header file from the specific set
of headers (listed in tools/perf/check-headers.sh), it is accompanied by
a commit that brings the same change into its counterpart located in
tools/include. Usually several changes are squashed together. We cannot
easily follow this strategy, since we not always take all the commits
squashed together.

In order to tidy tools/include up, we need to sync the headers manually.
