chore: Remove wrapper script for fail2ban service (#3032)

Browse source 
* chore: Remove the wrapper script for `fail2ban`

- This does not appear necessary. The server can be run with foreground mode.
- `daemons-stack.sh` removal of the socket can be handled by the fail2ban server when using the `-x` option.

* chore: Remove `touch /var/log/auth.log`

These were both added as supposed fixes in 2016 for the then Ubuntu 2014 base image.

Removing them causes no failures in tests.

* fix: Install optional python packages for `fail2ban`

These have barely any overhead in layer weight. The DNS package may provide some QoL improvements, while the `pyinotify` is a better alternative than polling logs to check for updates.

We have `gamin` package installed but `fail2ban` would complain in the log that it was not able to initialize the module for it. There only appears to be a `python-gamin` dependent on EOL python 2, no longer available from Debian Bullseye.
