Update file paths to reflect update to fluent-package

[SeamusClark]

update_fluentd_cfg.rb needs to be updated with the new paths for configuration files. The old paths

file_map_cfg_file = "/etc/td-agent/log-file-map.conf" old_file_map_cfg_file = "/etc/zebrium/log-file-map.cfg" user_fluentd_cfg_file = "/etc/td-agent/conf.d/user.conf"

need to be updated to reflect the updated paths /etc/fluent/ and /etc/fluent/conf.d. Any changes to the rest of the script or other components of the collector need to also be investigated and updated.
