[PATCH-for-9.0 07/10] sysemu/xen-mapcache: Check Xen availability with CONFIG_XEN_IS_POSSIBLE

[Philippe Mathieu-Daudé <philmd@xxxxxxxxxx>]

"sysemu/xen.h" defines CONFIG_XEN_IS_POSSIBLE as a target-agnostic
version of CONFIG_XEN. Use it in order to use "sysemu/xen-mapcache.h"
in target-agnostic files.
