test: allow extd_apicid CPU feature on AMD guests

PCI-enabled guest kernels enable the `extd_apicid` CPU feature for AMD
CPU families after 16h. Our supported AMD families (Milan & Genoa) are
both 19h. This is irrespective of whether PCI is enabled in Firecracker.

Do not mark this as host-only when running with PCI enabled kernels,
i.e. all kernels that support ACPI.
