    perf python: Fix up the build on architectures without HAVE_KVM_STAT_SUPPORT
    
    [ Upstream commit 758f18158952a6287ac23679ec04c32d44ca5368 ]
    
    Noticed while building on a raspbian arm 32-bit system.
    
    There was also this other case, fixed by adding a missing util/stat.h
    with the prototypes:
    
      /tmp/tmp.MbiSHoF3dj/perf-6.12.0-rc3/tools/perf/util/python.c:1396:6: error: no previous prototype for ‘perf_stat__set_no_csv_summary’ [-Werror=missing-prototypes]
       1396 | void perf_stat__set_no_csv_summary(int set __maybe_unused)
            |      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      /tmp/tmp.MbiSHoF3dj/perf-6.12.0-rc3/tools/perf/util/python.c:1400:6: error: no previous prototype for ‘perf_stat__set_big_num’ [-Werror=missing-prototypes]
       1400 | void perf_stat__set_big_num(int set __maybe_unused)
            |      ^~~~~~~~~~~~~~~~~~~~~~
      cc1: all warnings being treated as errors
    
    In other architectures this must be building due to some lucky indirect
    inclusion of that header.
