perf tests: Skip 'perf stat metrics (shadow stat) test' for hybrid
Currently we don't support shadow stat for hybrid. root@ssp-pwrt-002:~# ./perf stat -e cycles,instructions -a -- sleep 1 Performance counter stats for 'system wide': 12,883,109,591 cpu_core/cycles/ 6,405,163,221 cpu_atom/cycles/ 555,553,778 cpu_core/instructions/ 841,158,734 cpu_atom/instructions/ 1.002644773 seconds time elapsed Now there is no shadow stat 'insn per cycle' reported. We will support it later and now just skip the 'perf stat metrics (shadow stat) test'.
