Refactor Debian/Ubuntu package

Browse Source 
Move files for packaging outside the docs directory into its own
packaging directory. Replace the existing postinstall and postremove
scripts with Debian maintainerscripts to behave more like a typical
Debian package:

* Start and enable the headscale systemd service by default
* Does not print informational messages
* No longer stop and disable the service on updates

This package also performs migrations for all changes done in previous
package versions on upgrade:

* Set login shell to /usr/sbin/nologin
* Set home directory to /var/lib/headscale
* Migrate to system UID/GID

The package is lintian-clean with a few exceptions that are documented
as excludes and it passes puipars (both tested on Debian 12).

The following scenarious were tested on Ubuntu 22.04, Ubuntu 24.04,
Debian 11, Debian 12:

* Install
* Install same version again
* Install -> Remove -> Install
* Install -> Purge -> Install
* Purge
* Update from 0.22.0
* Update from 0.26.0

Open source implementation of the Tailscale control server.
Headscale aims to implement a self-hosted, open source alternative to the
Tailscale control server. Headscale's goal is to provide self-hosters and
hobbyists with an open-source server they can use for their projects and
labs. It implements a narrow scope, a single Tailscale network (tailnet),
suitable for a personal use, or a small open-source organisation.
