perf top: Add option --no-bpf-event
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
disabled 1
inherit 1
mmap 1
comm 1
freq 1
task 1
precise_ip 3
sample_id_all 1
exclude_guest 1
mmap2 1
comm_exec 1
ksymbol 1
bpf_event 1
------------------------------------------------------------
