perf tools: Accept case-insensitive symbolic event variants
We currently fail on something like '-e CPU-migrations', with:
invalid or unsupported event: 'CPU-migrations'
While 'CPU-migrations' is how we actually print out the event
in the default perf stat output:
Performance counter stats for 'true':
0.202204 task-clock-msecs # 0.282 CPUs
0 context-switches # 0.000 M/sec
0 CPU-migrations # 0.000 M/sec
So change the matching to be case-insensitive.
