Michal Privoznik fc216db4fb tests: Introduce viracpitest
Introduce a test that checks newly introduced virAcpi module.
There are three IORT tables from a real HW (IORT_ampere,
IORT_gigabyte and IORT_qualcomm), then there's one from a VM
(IORT_virt_aarch64) and one that I handcrafted to be empty
(IORT_empty).
