libvirt: use qemu (qdisk) disk driver for Xen >= 4.2.0

According to the Xen ML [1] "qdisk is better supported and blktap is
unmaintained, we choose qdisk over blktap whenever possible" (change was
introduced in Xen's commit 0166217 [2]). The Xen documentation states
that the disk driver "should not be specified, in which case libxl will
automatically determine the most suitable backend" [3]. However, even if
libvirt does it OK [4] not setting the driver name so that libxl chooses
the best backend, it sets the file format to 'raw' so that a wrong
backend will be chosen by libxl.  Since 'qdisk' seems to be the
preferred option, it seems safe to set it as the backend.
