[PATCH v2] perf kvm stat: Add missing mappings for PPC kvm exit reasons

[Gautam Menghani]

The macro kvm_trace_symbol_exit is used for providing the mappings
for the exit trap vectors and their names. Add mappings for H_FAC_UNAVAIL
and H_VIRT so that exit reasons are displayed as string instead of
vector numbers when using perf kvm stat.

Do we want to make a copy of the existing header in perf to keep things in sync
with check-headers.sh as suggested by Ian earlier?

Thanks,
