perf test: Print result for each BPF subtest

This patch prints each sub-tests results for BPF testcases.

Before:

  # ./perf test BPF
  37: Test BPF filter                                          : Ok

After:

  # ./perf test BPF
  37: Test BPF filter                                          :
  37.1: Test basic BPF filtering                               : Ok
  37.2: Test BPF prologue generation                           : Ok

When a failure happens:

  # cat ~/.perfconfig
  [llvm]
      clang-path = "/bin/false"
  # ./perf test BPF
  37: Test BPF filter                                          :
  37.1: Test basic BPF filtering                               : Skip
  37.2: Test BPF prologue generation                           : Skip
