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]
