Add image_types_swu class to support swu image type. To use this
in an image recipe following changes should be added in it:

 - inherit image_types_swu class
 - add SRC_URI with sw-description (and more required files)
 - add IMAGE_FSTYPES, i.e. "ext4.gz swu" or "ext4.gz.enc swu"
 - SWUPDATE_IMAGES_FSTYPES[core-image-full-cmdline] = ".ext4.gz"
 - IMAGE_DEPENDS = "core-image-full-cmdline"
 - SWUPDATE_IMAGES = "core-image-full-cmdline"
