This patch adds option --no-bpf-event to 'perf top', which is the same
as the option of 'perf record'.

The following patches will use this option.

Committer testing:

  # perf top -vv 2> /tmp/perf_event_attr.out
  # cat  /tmp/perf_event_attr.out
  ------------------------------------------------------------
  perf_event_attr:
    size                             112
    { sample_period, sample_freq }   4000
    sample_type                      IP|TID|TIME|CPU|PERIOD
    read_format                      ID
