import-debian-package: Create repository with CI disabled

When importing Debian packages it is possible to find cases where packages
already provided an upstream Gitlab CI configuration. In such cases,
when packages are imported Gitlab will try to run CI which has no sense.

For properly handle this scenario, create new repositories with CI
disabled, and let gitlab rulez to update the settings once the package
is fully imported.
