[wic][PATCH 14/20] wic: Fix naming conflict

[Ed Bartosh <ed.bartosh@linux.intel.com>]

Image file name is not unique for the partitions without label.
This causes image being rewritten and used as a source for all
partitions without label. Wic produces broken or incorrect result
images because of that.

Added wks line number to the image name to make it unique.
