include/trace/syscall.h: Use HAVE_SYSCALL_TRACEPOINTS instead of TRACEPOINTS

At present, most architectures can support TRACEPOINTS, but about 10/29 architectures support HAVE_SYSCALL_TRACEPOINTS.

TIF_SYSCALL_TRACEPOINT depends on HAVE_SYSCALL_TRACEPOINTS, not all architectures which support TRACEPOINTS also must support TIF_SYSCALL_TRACEPOINT.

So at present, need use HAVE_SYSCALL_TRACEPOINTS instead of TRACEPOINTS, or can not pass compiling. The related error (allmodconfig under score):

OK, thank you for replying in time.

Thanks.
