Description of problem:
Trying to write a test for logwatch, I have found that it ignores cafted log file passed via the --logdir option. The root cause seems to be that it converts the patch to lowercase.

Version-Release number of selected component (if applicable):
logwatch-7.4.3-21.el8.noarch

How reproducible:
always

Steps to Reproduce:
1. logwatch --service=fail2ban --range=all --logdir="/mnt/tests/CoreOS/logwatch/Regression/bz2043944-logwatch-for-fail2ban-should-ignore-Server-ready" --debug=6 2>/dev/null | grep logdir

Actual results:
logdir -> /mnt/tests/coreos/logwatch/regression/bz2043944-logwatch-for-fail2ban-should-ignore-server-ready

Expected results:
logdir -> /mnt/tests/CoreOs/logwatch/Regression/bz2043944-logwatch-for-fail2ban-should-ignore-server-ready
