[PATCH] configure: define CONFIG_XEN when Xen is enabled

From: Paul Durrant <pdurrant@xxxxxxxxxx>

The recent commit da278d58a092 "accel: Move Xen accelerator code under
accel/xen/" introduced a subtle semantic change, making xen_enabled() always
return false unless CONFIG_XEN is defined prior to inclusion of sysemu/xen.h,
which appears to be the normal case. This causes various use-cases of QEMU
with Xen to break.

This patch makes sure that CONFIG_XEN is defined if --enable-xen is passed
to configure.
