vl: Switch qemu_uuid to QemuUUID

Browse Source 
Update all qemu_uuid users as well, especially get rid of the duplicated
low level g_strdup_printf, sscanf and snprintf calls with QEMU UUID API.

Since qemu_uuid_parse is quite tangled with qemu_uuid, its switching to
QemuUUID is done here too to keep everything in sync and avoid code
churn.
