tools/include: Sync uapi/asm-generic/unistd.h with the kernel sources

Browse source 
And arch syscall tables to pick up changes from:

  b1e31c134a powerpc: restore some missing spu syscalls
  d3882564a7 syscalls: fix compat_sys_io_pgetevents_time64 usage
  54233a4254 uretprobe: change syscall number, again
  63ded11097 uprobe: Change uretprobe syscall scope and number
  9142be9e64 x86/syscall: Mark exit[_group] syscall handlers __noreturn
  9aae1baa1c x86, arm: Add missing license tag to syscall tables files
  5c28424e9a syscalls: Fix to add sys_uretprobe to syscall.tbl
  190fec72df uprobe: Wire up uretprobe system call

This should be used to beautify syscall arguments and it addresses
these tools/perf build warnings:

  Warning: Kernel ABI header differences:
  diff -u tools/include/uapi/asm-generic/unistd.h include/uapi/asm-generic/unistd.h
  diff -u tools/perf/arch/x86/entry/syscalls/syscall_64.tbl arch/x86/entry/syscalls/syscall_64.tbl

  diff -u tools/perf/arch/s390/entry/syscalls/syscall.tbl arch/s390/kernel/syscalls/syscall.tbl

Please see tools/include/uapi/README for details (it's in the first patch
of this series).
