The debian package build usually detects dependencies of executables packaged inside, and adds those as dependencies of the package accordingly. It doesn't detect this for managed executables though, so libcurl3 needs to be added to support `dotnet restore` on Ubuntu.
The long description format is somewhat fragile right now. Changes will need to be made to the package tool to handle this better because each line in the long description needs a leading space.
These changes will use docker's new Dockerfile Arguments to
pass the Host User ID to the docker container at build time.
This allows the docker container to set it's internal user
to match that of the host. When using shared volumes between
the host and container, this prevents files created in the
container from being owned by root.
This will solve our problem of needing a cleanup step after
every ubuntu CI run.
