[OE-core] [PATCH 2/3] image types: add bmap generation option

[Ed Bartosh]

From: "Alexander D. Kanevskiy" <kad at kad.name>

bmap image conversion type allows to create block map files
for sparse images. Bmap file can be used together with bmap-tools
for efficiently flash images to raw devices (hdd or usb drive)
