selftests/powerpc: Run per_event_excludes test on Power8 or later
The per_event_excludes test wants to run on Power8 or later. But
currently it checks that AT_BASE_PLATFORM *equals* power8, which means
it only runs on Power8.
Fix it to check for the ISA 2.07 feature, which will be set on Power8
and later CPUs.
