perf evsel: Fix the annotation for hardware events on hybrid
The annotation for hardware events is wrong on hybrid. For example,
# ./perf stat -a sleep 1
Performance counter stats for 'system wide':
32,148.85 msec cpu-clock # 32.000 CPUs utilized
374 context-switches # 11.633 /sec

1,016,336 cpu_atom/branch-misses/ # 31.613 K/sec (63.38%)
The hardware events have extended type on hybrid, but the evsel__match()
doesn't take it into account.
Filter the config on hybrid before checking.
With the patch,
# ./perf stat -a sleep 1
Performance counter stats for 'system wide':
