[[PATCH v2]] bmap: generate bmap for wic images

[Daniel Sangorrin <daniel.sangorrin@toshiba.co.jp>]

bmap shortens the time required to flash an image.
This can be useful when you need a fixed-size image, for
example to update partitions with swupdate.

Example usage:
sudo bmaptool copy --bmap \
build/tmp/deploy/images/iwg20m/cip-core-image-cip-core-iwg20m.wic.img.bmap \
build/tmp/deploy/images/iwg20m/cip-core-image-cip-core-iwg20m.wic.img \
/dev/sdf
