[PATCH 21/25] perf evsel: Switch to libperf's cpumap.h

We don't need what is in perf's util/cpumap.h, just the struct cpu_map
that is in libperf's internal/cpumap.h file to cover this one case:

tools/perf/util/evsel.h:215:27: error: dereferencing pointer to incomplete type âstruct perf_cpu_mapâ
215 | return evsel__cpus(evsel)->nr;

So switch to libperf's cpumap.h and add some missing struct foward
declarations and include sys/types.h to get pid_t.
