image_types: use compress framework to produce checksums for images 

Existing compress framework for producing various compressed versions
of images is powerfull enough to be extended for other uses, e.g. to
convert types of images.

It is possible to use it also to produce image checksums at the time
of image generation. This commit adds support for all supported
at the moment coreutils hashing algorithms: md5, sha1, sha224,
sha256, sha384 and sha512

Usage:
IMAGE_FSTYPES_append = " hddimg.sha256sum"
