x86: ioapic: Run physical destination mode test iff cpu_count() > 1
Make test_ioapic_physical_destination_mode() depending on having at
least two CPUs as it sets ->dest_id to '1', i.e. expects CPU0 and CPU1
to exist. This analysis is backed up by the fact that the test was
originally gated by cpu_count() > 1.
