gitlab-ci: test re-buildability of distribution tarballs

Adds tests for making a distribution tarball, and then attempting to build NM from its contents.
Files have been left out from the distribution in the past by accident (e.g. 75027879, b2931c96)
and hopefully this test will catch this type of errors.
