Add additional ignore entries

[jrusz]

This repo is no longer being maintained. In order to get at least some testing for new nightlies I'm adding all currently failing entries to the db-ignore file. Most of them are ostree/edge which should not work here in the first place.

Considering this repo is basically in deprecation mode we agreed with @lavocatt that makes sense to just add all the currently failing test cases to the db-ignore to get at least some testing on the new nightlies before this can be taken over by the images repository. Most of them are edge type images which should be there in the first place, the only one that really stood out to me is ova image type. I just hope it won't create a false sense of "all is good" but since we're testing all the important image types in integration tests in osbuild-composer repository I think we should be good. The pipeline passed here https://gitlab.com/redhat/services/products/image-builder/ci/manifest-db/-/pipelines/1100165687 when I tried it manually before opening this MR and Schutzbot even created a PR to update the db: #99

What do you think about this @atodorov @achilleas-k ?

I think that's fine. I have some thoughts about changing this repo to download images and manifests from the ones that are generated in osbuild/images CI and maintain image-info on those, as a reference database. But no one has time to work on that now so let's keep this as it is for now, make it green, and revisit it another time.
