wic: fix processing of --use-uuid

Processing of this option was lost during recent change of
wks parsting. It was discovered during the work on booting
wic images under qemu. Now, when -use-uuid is fixed it's
possible to specify root partition by partition uuid.
This will be done in the following commit.
