Our config moved into /etc/logrotate.d/pihole a while back, so the system's own scheduled logrotate now picks it up too. Our nightly and @reboot forced runs were still using a private state file though, so the system's run and ours each rotated the same logs independently, unaware of each other. Drop the private state file and use logrotate's default one instead, so both sides agree on what's already been rotated. Also clean up the now-stale /etc/pihole/logrotate and private state file left behind by older installs. Signed-off-by: Adam Warner <me@adamwarner.co.uk>
