libperf: Use 'extern' in LIBPERF_API visibility macro 



Use 'extern' on LIBPERF_API to address this issue that started appearing
with gcc 15, first seen in ubuntu 25.10:

  evlist.c: In function 'perf_evlist__purge':
  evlist.c:202:17: error: implicit declaration of function 'perf_evsel__delete'; did you mean 'perf_evsel__exit'? [-Wimplicit-function-declaration]
    202 |                 perf_evsel__delete(pos);
        |                 ^~~~~~~~~~~~~~~~~~
        |                 perf_evsel__exit
  evlist.c:202:17: error: nested extern declaration of 'perf_evsel__delete' [-Werror=nested-externs]
  evlist.c: In function 'perf_evlist__open':
  evlist.c:261:23: error: implicit declaration of function 'perf_evsel__open'; did you mean 'perf_evsel__exit'? [-Wimplicit-function-declaration]
    261 |                 err = perf_evsel__open(evsel, evsel->cpus, evsel->threads);
        |                       ^~~~~~~~~~~~~~~~
        |                       perf_evsel__exit
  evlist.c:261:23: error: nested extern declaration of 'perf_evsel__open' [-Werror=nested-externs]
