perf pmu: Recognize default_core as a core PMU in more places
The python metrics code used in places like ilist.py passes a
pmu-filter of "default_core" on non-hybrid x86/ARM/.. systems. As a
PMU like "cpu" isn't a literal name match then no PMU matches
"default_core" and the events fail to parse for the metric. Fix the
name matching and PMU lookup for "default_core" and check that it
fixes ilist.py.
Fixes: 74e2dbe7be50 ("perf tools: Add --pmu-filter option for filtering PMUs")
