perf list: Don't print Unit for "default_core" 

"default_core" was added as a way to demark JSON events whose PMU should
be whatever the default core PMU is, previously this had been assumed to
be "cpu" but that fails on s390 and ARM.

'perf list' displays the PMU in the event description to save storing it
in JSON, but was still comparing against "cpu" and not "default_core",
so update this.

Fixes: d2045f8715 ("perf jevents: Use "default_core" for events with no Unit")
