wic: Switch to using --use-uuid by default

The most portable way to specifiy a root device in a disk image that we
create is to use PARTUUID rather than /dev/sda2.  As background, both
GPT and MBR tables provide valid UUID values for each partition and the
Linux Kernel contains the logic to parse this value.  With this change
we can now boot the default disk images when used as any valid block
device that the included kernel uses.  This for example means that
VirtualBox can be used to run vmdk without changes as it uses IDE for
the virtual disk controller.
