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:
ff388fe5c481d39c ("mseal: wire up mseal syscall")
2883f01ec37dd866 ("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 ([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:
