[PATCH v16 65/99] tests: device-introspect-test: cope with ARM TCG-only devices

[Alex Bennée]

From: Claudio Fontana <cfontana@suse.de>

Skip the test_device_intro_concrete for now for ARM KVM-only build,
as on ARM we currently build devices for ARM that are not
compatible with a KVM-only build.

We can remove this workaround when we fix this in KConfig etc,
and we only list and build machines that are compatible with KVM
for KVM-only builds.

Alternative implementation provided by Alex.
