perf/record: simplify TRACE_INFO tracepoint check

Fix a couple of inefficiencies and redundancies related to
have_tracepoints() and its use when checking whether to write
TRACE_INFO.

First, there's no need to use get_tracepoints_path() in
have_tracepoints() - we really just want the part that checks whether
any attributes correspondo to tracepoints.

Second, we really don't care about raw_samples per se - tracepoints
are always raw_samples.  In any case, the have_tracepoints() check
should be sufficient to decide whether or not to write TRACE_INFO.
