[PATCH] tests: Adjust libxlxml2domconfigtest to work with Xen < 4.10



Commit f253dc90f5 introduced a test regression in environments with
Xen < 4.10. The logic in libxl_conf.c correctly maps ACPI and APIC
from virDomainObj to libxl_domain_conf based on
LIBXL_HAVE_BUILDINFO_APIC, but the tests did not account for the
different libxl_domain_conf JSON representations.

One approach to fixing the test regression is to duplicate JSON test
data files, having one set for Xen <= 4.9 and another for Xen 4.10
and greater. To avoid duplicate data files, this patch takes the
approach of modifying the libxl_domain_conf object based on
LIBXL_HAVE_BUILDINFO_APIC, before retrieving the JSON representation.
It allows using the same test data files for all supported versions
of Xen by adjusting the intermediate form of libxl_domain_conf object
as needed.
