Subject: [PATCH 34/36] libperf: Keep count of failed tests

Keeping the count of failed tests, so we
get better output with failures, like:

  # make tests
  ...
  running static:
  - running test-cpumap.c...OK
  - running test-threadmap.c...OK
  - running test-evlist.c...FAILED test-evlist.c:53 failed to create evsel2
  FAILED test-evlist.c:163 failed to create evsel2
  FAILED test-evlist.c:287 failed count
    FAILED (3)
  - running test-evsel.c...OK
  running dynamic:
  - running test-cpumap.c...OK
  - running test-threadmap.c...OK
  - running test-evlist.c...FAILED test-evlist.c:53 failed to create evsel2
  FAILED test-evlist.c:163 failed to create evsel2
  FAILED test-evlist.c:287 failed count
    FAILED (3)
  - running test-evsel.c...OK
 ...
