[PATCH v2] libxl: include a XLU_Config in _libxlDriverConfig

[Olaf Hering <olaf@xxxxxxxxx>]

Upcoming changes for vscsi will use libxlutil.so to prepare the
configuration for libxl. The helpers needs a xlu struct for logging.
Provide one and reuse the existing output as log target.

v2:
 - call xlu_cfg_destroy, unconditionally
 - fix cpp indention in libxl_conf.h
