Determine if a metric is default from `perf list --raw-dump $m` eg:
```
$ perf list --raw-dump l1_prefetch_miss_rate
Default4 l1_prefetch_miss_rate
```
If a metric has "not supported" or "no supported events" then ignore
these failures for default metrics. Tidy up the skip/fail messages in
the output to make them easier to spot/read.
