📄 Description

Describe your changes

Some distros use util-linux's login binary, which doesn't work with NetBird's SSH.
Debian, for example, started using this binary recently in Debian 13, which broke NetBird's SSH.
runuser is the recommended utility for this use case and is now tried first on all Linux systems.
If runuser doesn't exist, it falls back to the standard login method.
I also removed the special handling for arch-linux, since it just uses runuser for that distro now.
