Revert "CI: Add bootimg analysis integration test (MR 2467)" (MR 2483)

This test includes a binary blob which we want to avoid in our codebase.

It is also better suited as a unit test where it can contribute to code
coverage. Revert this and use a unit test version instead.

This reverts commit d19de946b3.
