perf python: Improve the tracepoint function if no libtraceevent
The tracepoint function just returns the tracepoint id, this doesn't
require libtraceevent which is only used for parsing the event format
data.
Implement the function using the id function in tp_pmu. No current code
in perf is using this, the previous code migrated to perf.parse_events,
but it feels good to have less ifdef HAVE_LIBTRACEEVENT.
