trivial: Fix irrelevant-files regexes for unit tests

This is to fix the regexes for unit tests in irrelevant-files
in .zuul.yaml to avoid unnecessarily running unit tests. Currently
the regex includes "patrole/" which is incorrect as the "root"
should be the topmost patrole package in the project's repo
which is "patrole_tempest_plugin".
