bitbake: toaster: display Target targets in build dashboard

The build dashboard was showing the targets for the build in the page
heading and title as "Target object".

Add a filter which extracts the "target" from each Target object
as a string so that the heading and title display correctly.

Also sort the image file suffixes alphabetically.
