Philippe Mathieu-Daudé 8e0ef06894 accel/xen: Fix xen_enabled() behavior on target-agnostic objects
CONFIG_XEN is generated by configure and stored in "config-target.h",
which is (obviously) only include for target-specific objects.
This is a problem for target-agnostic objects as CONFIG_XEN is never
defined and xen_enabled() is always inlined as 'false'.

Fix by following the KVM schema, defining CONFIG_XEN_IS_POSSIBLE
when we don't know to force the call of the non-inlined function,
returning the xen_allowed boolean.

Fixes: da278d58a0 ("accel: Move Xen accelerator code under accel/xen/")
