[libvirt] [PATCH v4 08/42] remote: conditionalize driver loading in libvirtd daemon

Prepare for reusing libvirtd source to create other daemons by making the driver(s) to load conditionally defined by the make rules. If nothing is set, all drivers will be loaded, ignoring any missing ones as historically done. If MODULE_NAME is set only one driver will be loaded and that one must succeed.
