perf util: Use evsel->name to get tracepoint_paths
Most tracepoint events already have their system and event name in
->name field so that searching whole event tracing directory for each
evsel to match given id is suboptimal.
Factor out this routine into tracepoint_name_to_path(). In case of en
invalid name, it'll try to find path using id again.
