…mfd_secret syscall

To pick the changes in these csets:

  7608f70 ("s390: wire up memfd_secret system call")

That add support for this new syscall in tools such as 'perf trace'.

For instance, this is now possible (adapted from the x86_64 test output):

  # perf trace -v -e memfd_secret
  event qualifier tracepoint filter: (common_pid != 13375 && common_pid != 3713) && (id == 447)
  ^C#

That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.

  $ grep memfd_secret tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
  447    common  memfd_secret            sys_memfd_secret
  $

This addresses this perf build warnings:

  Warning: Kernel ABI header at 'tools/perf/arch/s390/entry/syscalls/syscall.tbl' differs from latest version at 'arch/s390/kernel/syscalls/syscall.tbl'
  diff -u tools/perf/arch/s390/entry/syscalls/syscall.tbl arch/s390/kernel/syscalls/syscall.tbl
