watchdog: xen_wdt: fix potential build failure 



xen_wdt uses watchdog core functions (from watchdog_core.c) and, when
compiled without CONFIG_WATCHDOG_CORE being set, it produces the
following build error:

ERROR: "devm_watchdog_register_device" [drivers/watchdog/xen_wdt.ko] undefined!
ERROR: "watchdog_init_timeout" [drivers/watchdog/xen_wdt.ko] undefined!

Fix this by selecting CONFIG_WATCHDOG_CORE when CONFIG_XEN_WDT is set.
