tracing: Documentation / sample code fixes for tracepoints
Fix the tracepoint documentation to refer to "tracepoint-sample"
instead of "tracepoint-example" to match what actually exists;
fix the directory, and clarify how to compile.
Change every instance of "example" in the sample tracepoint code
to "sample" for consistency.
