Filebeat: apache2(httpd) log path add to module manifest

Fedora, RHEL7 apache package (httpd) create logs to
'/var/log/httpd' instead of '/var/log/apache2' directory,
and the log files are named as '*_log' instead of '.log' format.

To make Filebeat apache2 module work out of the box on these
environments, add '/var/log/httpd/*_log' pattern to the manifest
file will solve this problem.

Fixed: elastic#11887
