Don't inherit image-overlay by default

This attempts to address a race condition in the build where
we attempt to build a complete flash image before all the sub-images
are available (specifically the initramfs image).

Any classes in IMAGE_CLASSES are inherited by all image recipes, including
the initramfs image.  OE-Core's live/hddimg recipes address this
by pulling in the class configuration in recipe scope, rather than
global scope.  Copy that behavior here.
