Remove compression and count from logrotate

[sbraz]

Initially reported at https://bugs.gentoo.org/show_bug.cgi?id=549856
As the reporter mentioned, the count parameter means logs are deleted regardless of the global logrotate config; the compression setting should also inherit the global defaults.

sounds sensible to me (I will let this issue age a bit to hear other @fail2ban/developers and @fail2ban/contributors )... I wonder though why so many logrotate configs on my debian system has those specified explicitly...

Sometime it is critical to find a 4 months old mail server log line or PayPal IPN in Apache's log.

sure, but the question is more of either Fail2Ban should inherit
settings from the main logrotate configuration or have its own "opinion"
on the defaults ;)

Let's say the max bantime is 1 week ([recidive]). Logrotate's default is 4×weeks, so I would merge this PR.
