This test case demonstrates how to explicitly opt into using
the uefi-vars device for an aarch64 guest.

Normally the firmware autoselection process will pick a UEFI
build that is loaded via pflash, but by including the <varstore>
element in the input XML we can tell the QEMU driver that we
want want the uefi-vars device to be used instead.

Currently this results in an error, because the firmware
autoselection algorithm doesn't yet know how to properly handle
the scenario. A future commit will address this and make things
work as expected.
