tools include powerpc: Update arch/powerpc/include/uapi/asm/unistd.h copy to get 'rseq' syscall

This updates the tools/perf/ copy of the powerpc file used to generate
the syscall table file used to make 'perf trace' become aware of the new
'rseq' syscall, no matter in which system it gets built, i.e. older
systems where the syscalls are not available in the running kernel (via
tracefs) or in the system headers will still be aware of these
syscalls/.
