[PATCH 16/28] tools arch uapi: Update asm-generic/unistd.h and arm64 unistd.h copies

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

To get the changes in:

  82b355d161c9 ("y2038: Remove newstat family from default syscall set")

Which will make the syscall table used by 'perf trace' for arm64 to be
updated from the changes in that patch.

This silences these perf build warnings:
