The strncpy() function may leave the destination string buffer
unterminated, better use strlcpy() that we have a __weak fallback
implementation for systems without it.
This fixes this warning on an Alpine Linux Edge system with gcc 8.2:
util/header.c: In function 'perf_event__synthesize_event_update_name':
util/header.c:3625:2: error: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation]
strncpy(ev->data, evsel->name, len);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
util/header.c:3618:15: note: length computed here
size_t len = strlen(evsel->name);
^~~~~~~~~~~~~~~~~~~
