perf tools: Fix tracepoint id to string perf.data header table
It was broken by f006d25 that passed just the event name, not the complete
sys:event that it expected to open the /sys/.../sys/sys:event/id file to get
the id.
Fix it by moving it to after parse_events in cmd_record, as at that point
we can just traverse the evsel_list and use evsel->attr.config +
event_name(evsel) instead of re-opening the /id file.
