Fix packages verification

[kbgl]

Use correct docker image for packages verification (-source instead of -build) - that image has lintian installed during image creation.

@kbgl only rhel build is successful. Rest all the builds are failing with the following error: `W: golang-virtual: new-package-should-close-itp-bug

@kbgl This PR is failing bionic arm64 build because the current dev branch has the broken build for bionic arm64 as this PR #181 was merged even though PR checks did not pass for it. I have already created the defect Jira ticket for it.
Since all the other build combinations are successfully passing for your PR, I would say it is safe to assume that it will work for bionic arm64 too.

FYI, the bionic arm64 fluentbit build has been fixed
