* feat(debian) enable module to work on debian
Add support for Debian based on the documentation in debian wiki
and discussion in [0].
[0]: https://github.com/githubixx/ansible-role-wireguard/issues/5
* remove run_once for debian
* Install kernel headers on debian
There is no equivalent package of linux-headers-generic on debian.
Package installation needs to specify the architecture (i.e. amd64),
which is captured from dpkg output.
* Only use include_tasks to differentiate distributions
Before Archlinux was split out using ansible_os_family. But since
ansible_os_family overlaps for Debian and Ubuntu, two when
statements were used to split out these cases:
- All arch derivations
- Debian
- Ubuntu
New style is cleaner. Arch derivations can still be used by
overiding ansible_distribution in inventory.
* incorporate feedback: move pin file, other changed_when syntax
