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.

perf tests stat_bpf_counters: Fix usage of '==' to address shellcheck warning
Running shellcheck on stat_bpf_counter.sh generates below warning:
In tests/shell/stat_bpf_counters.sh line 34: if [ "$base_cycles" == "<not" ]; then ^-- SC3014 (warning): In POSIX sh, == in place of = is undefined.
In tests/shell/stat_bpf_counters.sh line 39: if [ "$bpf_cycles" == "<not" ]; then ^-- SC3014 (warning): In POSIX sh, == in place of = is undefined.
Fix this by using "=" instead of "==" to work for all shells.
