Fix for #10835 - WIC should not rely on hddimg creation for finding all needed artifacts

Hi,

This patchset usage of hddimg from wic codebase due to planned deprecation of hddimg.

While working on this wic-related code in meta/classes/ has been moved to image-wic.bbclass to make it more maintainable.

Changes in v2: rebased on top of ross/mut
Changes in v3: removed patches that add tasks, fixed test cases,
rebased on top of patches that make use of artifacts from DEPLOY_DIR_IMAGE, rebased on to pf ross/mut

The following changes since commit 2624674adefd86d15bc0bec2bb2a3876f785b947:

selftest: check results in test_image_vars_dir* (2017-01-27 17:27:30 +0000)
