Subject: [PATCH 29/41] perf script: Remove superfluous BPF event titles

From: Jiri Olsa <jolsa@...nel.org>

There's no need to display "ksymbol event with" text for the
PERF_RECORD_KSYMBOL event and "bpf event with" test for the
PERF_RECORD_BPF_EVENT event.

Remove it so it also goes along with other side-band events display.

Before:

  # perf script --show-bpf-events
  ...
  swapper     0 [000]     0.000000: PERF_RECORD_KSYMBOL ksymbol event with addr ffffffffc0ef971d len 229 type 1 flags 0x0 name bpf_prog_2a142ef67aaad174
  swapper     0 [000]     0.000000: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 36

After:

  # perf script --show-bpf-events
  ...
  swapper     0 [000]     0.000000: PERF_RECORD_KSYMBOL addr ffffffffc0ef971d len 229 type 1 flags 0x0 name bpf_prog_2a142ef67aaad174
  swapper     0 [000]     0.000000: PERF_RECORD_BPF_EVENT type 1, flags 0, id 36
