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

From: Arnaldo Carvalho de Melo <acme@...hat.com>

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 ‘struct perf_cpu_map’
  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.
