perf pmu: Drop "default_core" from alias names
"default_core" is used by jevents.py for json events' PMU name when
none is specified. On x86 the "default_core" is typically the PMU
"cpu". When creating an alias see if the event's PMU name is
"default_core" in which case don't record it. This means in places
like "perf list" the PMU's name will be used in its place.
Before:
$ perf list --details
...
cache:
l1d.replacement
[Counts the number of cache lines replaced in L1 data cache]
default_core/event=0x51,period=0x186a3,umask=0x1/
...
After:
$ perf list --details
...
cache:
l1d.replacement
[Counts the number of cache lines replaced in L1 data cache. Unit: cpu]
cpu/event=0x51,period=0x186a3,umask=0x1/
...
