[libvirt] [PATCH]util: Helper function for checking existence of hook files for specific driver

From: Chen Hanxiao <chenhanxiao(a)cn.fujitsu.com&gt; We refresh the status of hook scripts only when start/restart libvirt or reloads its configuration. But hooks scripts may be changed. This function will help to check its existence. And we do not need to start/restart libvirt if we add/remove hook files.
