Jiri Olsa 301a89f8cf libperf: Keep count of failed tests
Keep 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
