unix: extend support for z/OS
This change syncs the IBM internal version of sys/unix with the public repository. There are a variety of new syscalls and const definitions that have been accumulated over the past few years to support developers using Go on the platform. Old simulations of calls like 'epoll' and 'fstatfs' have been replaced with their real counterparts. The zos/s390x syscalls also have extensive trampolining to handle zos systems that might not have support for some of these new system calls. Closes golang/go#67071 Change-Id: I973d9e0abca2b05365308cf2b890438e50ae5957 Reviewed-on: https://go-review.googlesource.com/c/sys/+/582035 Reviewed-by: David Chase <drchase@google.com> Reviewed-by: Bill O'Farrell <billotosyr@gmail.com> Reviewed-by: Ian Lance Taylor <iant@google.com> Auto-Submit: Ian Lance Taylor <iant@google.com> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com>
