perf tools: Fix strlen() bug in perf_event__synthesize_event_type()
The event_type record has a max length for the event name.
It's called MAX_EVENT_NAME.
The name may be truncated to fit the max length. But the header.size still
reflects the original name length. If that length is > MAX_EVENT_NAME, then the
header.size field is bogus. Fix this by using the length of the name after the
potential truncation.
