fail2ban: 0.11.2 -> 1.0.2

Update to 1.0.2: https://github.com/fail2ban/fail2ban/blob/1.0.2/ChangeLog#ver-102-20221109---finally-war-game-test-tape-not-a-nuclear-alarm
1.0.1 contained a few breaking changes, but I think they have little
impact.

I changed the module to use the systemd service shipping with fail2ban
(now added to the package).

 - The EC2 image module previously detected and activated swap-formatted instance store devices and partitions in stage-1 (initramfs). This behaviour has been removed. Users relying on this should provide their own implementation.
 
+- `fail2ban` has been updated to 1.0.2, which has a few breaking changes compared to 0.11.2 ([changelog for 1.0.1](https://github.com/fail2ban/fail2ban/blob/1.0.1/ChangeLog), [changelog for 1.0.2](https://github.com/fail2ban/fail2ban/blob/1.0.2/ChangeLog))
+
 - Calling `makeSetupHook` without passing a `name` argument is deprecated.
 
 - Qt 5.12 and 5.14 have been removed, as the corresponding branches have been EOL upstream for a long time. This affected under 10 packages in nixpkgs, largely unmaintained upstream as well, however, out-of-tree package expressions may need to be updated manually.
