bitbake: toaster: the customise image button shouldn't rely on targets

The build dashboard customise image button (for creating a new
custom image based on an image recipe used by a build) shouldn't
rely on targets: whether a new custom image can be created or not
depends on whether any of the recipes used by the build are image
recipes.

Modify the method used to determine whether a build has customisable
images to look at the image recipes used during the build, rather
than whether the targets run by the build refer to image recipes.
