    Revert "wic/utils/partitionedfs.py: assemble .wic images as sparse files"
    
    It turns out that dd's conv=sparse doesn't look at the file extents, but simply
    checks if a "block" is all zero.  If the block of zero was meaningful it gets
    lost and if the image is subsequently written to media using a sparse-aware
    writer then the block of zeros won't be written at all.
    
    This reverts commit 5fd592fbae2e046bcb8c3a6c3ef4993fe0400676.
