Lubomír Sedlář 4e3d87e658 [test] Add checks for created images
The performed checks:
 * If format is ISO, the file must have correct magic string
 * If it's bootable, there must be MBR or GPT

When a check fails on any failable deliverable, it will be logged and
the file removed from metadata (it will still remain on the disk). This
required a change to write the images.json file later (after test
phase).
