Add bzip2 dependency for perf tool
    
    Adding explicit bzip2 dependency for perf tool. The bzip2
    is used in perf archive script command, and without bzip2
    command it fails, like:
    
      $ perf archive
      tar (child): bzip2: Cannot exec: No such file or directory
      tar (child): Error is not recoverable: exiting now
    
    With explicit bzip2 dependency we're ok:
      $ rpm -qp --requires perf-...rpm  | grep bzip2
      bzip2
