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'.
