perf test shell stat_bpf_counters: Fix test on Intel
As of now, bpf counters (bperf) don't support event groups. But the
default perf stat includes topdown metrics if supported (on recent Intel
machines) which require groups. That makes perf stat exiting.
$ sudo perf stat --bpf-counter true
bpf managed perf events do not yet support groups.
Actually the test explicitly uses cycles event only, but it missed to
pass the option when it checks the availability of the command.
Fixes: 2c0cb9f56020d2ea ("perf test: Add a shell test for 'perf stat --bpf-counters' new option")
