Arnaldo Carvalho de Melo da42b5229b tools headers: Update the syscall tables and unistd.h, mostly to support the new 'mseal' syscall 
But also to wire up shadow stacks on 32-bit x86, picking up those
changes from these csets:

  ff388fe5c4 ("mseal: wire up mseal syscall")
  2883f01ec3 ("x86/shstk: Enable shadow stacks for x32")

This makes 'perf trace' support it, now its possible, for instance to
do:

  # perf trace -e mseal --max-stack=16

Here is an example with the 'sendmmsg' syscall:

  root@x1:~# perf trace -e sendmmsg --max-stack 16 --max-events=1
       0.000 ( 0.062 ms): dbus-broker/1012 sendmmsg(fd: 150, mmsg: 0x7ffef57cca50, vlen: 1, flags: DONTWAIT|NOSIGNAL) = 1
                                         syscall_exit_to_user_mode_prepare ([kernel.kallsyms])
                                         syscall_exit_to_user_mode_prepare ([kernel.kallsyms])
                                         syscall_exit_to_user_mode ([kernel.kallsyms])
                                         do_syscall_64 ([kernel.kallsyms])
                                         entry_SYSCALL_64 ([kernel.kallsyms])
                                         [0x117ce7] (/usr/lib64/libc.so.6 (deleted))
  root@x1:~#

To do a system wide tracing of the new 'mseal' syscall with a backtrace
of at most 16 entries.

This addresses these perf tools build warnings:

  Warning: Kernel ABI header differences:
