perf test: Fix "all PMU test" to skip hv_24x7/hv_gpci tests on powerpc

Browse Source 
"perf all PMU test" picks the input events from "perf list --raw-dump
pmu" list and runs "perf stat -e" for each of the event in the list. In
case of powerpc, the PowerVM environment supports events from hv_24x7
and hv_gpci PMU which is of example format like below:

- hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/
- hv_gpci/event,partition_id=?/

The value for "?" needs to be filled in depending on system and
respective event. CPM_ADJUNCT_INST needs have core value and domain
value. hv_gpci event needs partition_id.  Similarly, there are other
events for hv_24x7 and hv_gpci having "?" in event format. Hence skip
these events on powerpc platform since values like partition_id, domain
is specific to system and event.
