perf test: Add a shell test for 'perf stat --bpf-counters' new option
Add a test to compare the output of perf-stat with and without option
--bpf-counters. If the difference is more than 10%, the test is considered
as failed.
Committer testing:
# perf test bpf-counters
86: perf stat --bpf-counters test : Ok
# perf test -v bpf-counters
86: perf stat --bpf-counters test :
--- start ---
test child forked, pid 2433339
test child finished with 0
---- end ----
perf stat --bpf-counters test: Ok
