[OE-core] [wic][PATCH 4/9] wic: Refactored getting root device name

Replaced DirectImageCreator._get_boot_config private method with a 'rootdev' property. Simplified the code and API. Used 'uuid' property instead of incorrectly used 'part_type'. Signed-off-by: Ed Bartosh diff --git a/scripts/lib/wic/imager/direct.py b/scripts/lib/wic/imager/direct.py index 83f96
