perf parse-events: Avoid regrouped warning for wild card events

There is logic to avoid printing the regrouping warning for wild card
PMUs, this logic also needs to apply for wild card events.

Before:
```
$ perf stat -e '{data_read,data_write}' -a sleep 1
WARNING: events were regrouped to match PMUs

 Performance counter stats for 'system wide':

          2,979.16 MiB  data_read
            410.26 MiB  data_write

       1.001541923 seconds time elapsed
```
After:
```
$ perf stat -e '{data_read,data_write}' -a sleep 1

 Performance counter stats for 'system wide':

          2,975.94 MiB  data_read
            432.05 MiB  data_write

       1.001119499 seconds time elapsed
```
