Fix irc-meetings publishing

The periodic job fails, example:
https://zuul.opendev.org/t/openstack/build/85f380fb6dde462e85a09bc9b5105ba9/

error is:
rsync: change_dir "/home/zuul//src/opendev.org/openstack/project-config/output" failed: No such file or directory (2)

Problem is that the output directory is in the irc-meetings directory
instead.

Use correct path.
