bitbake: toaster: use has_images() methods to display images correctly

In the build dashboard, we had issues with showing images correctly,
as we were using the is_image property of targets to determine
whether a target would have image files. This property can
be set to True if a target refers to an image recipe
(e.g. "core-image-minimal"), even if the task used in the build
didn't produce any image files.

By adding has_images() methods to the Target and Build objects,
which count associated Target_Image_File objects,
we can correctly determine whether a target has image files
associated with it, and if any of the targets for a build has
image files. This means that we can screen out the left-hand
"Images" menu options for builds which contained image-related
targets (e.g. "core-image-minimal") but which didn't produce
any images (e.g. "rootfs" task).
