KVM: PPC: Book3S HV: Add missing mappings for tracing exits

Browse Source 
The macro kvm_trace_symbol_exit is used for providing the mappings
for the trap vectors and their names. Add mappings for H_FAC_UNAVAIL and
RETURN_TO_HOST so that trap reasons are displayed as string instead of
vector numbers when using the kvm_guest_exit tracepoint.
