Hi!

While rebuilding the python related packages against the Python 3.15rc1
version we found that nordugrid-arc fails to build from source [1].

This is caused by credentials being generated and used concurrently,
which causes a race between the tests.

To fix this (and other related issues), I needed to:
- Patch to generate the credentials before launching the tests
- Patch upstream code to avoid mangling the debian folder
- Set the import name for the smoke autopkgtest test

I applied these fixes in the sandbox [2] to be able to build the
packages that depend on nordugrid-arc, please consider applying them to
support the upcoming 3.15 version.

Happy hacking,
