[OE-core] [PATCH 6/8] image_types_wic: set default WKS_FILE_DEPENDS

[Ed Bartosh]

The default set of dependencies used via wic-tools is not used
anymore as wic images don't depend on wic-tools.

Set of packages required to produce wic image depends on the content
of the .wks file, so WKS_FILE_DEPENDS variable should be used to
provide correct list of dependencies when WKS_FILE variable is set.

As WKS_FILE_DEPENDS is not used in many existing recipes yet we need
to provide default value for it to ensure that removal of wic-tool
dependency doesn't cause image build failures.

Initialized WKS_FILE_DEPENDS with the set of dependencies previously
brought by wic-tool. This is done to provide compatibility and to
avoid breakages of existing image recipes that rely on current set
of dependencies.

Note: This is a temporary solution for transition period.
After some time the list will be either reduced or removed.
Recommended solution is to use WKS_FILE_DEPENDS in image recipes
together with WKS_FILE to specify dependencies.
