Subject: [PATCH] [CI] Replace deprecated regex

Latest Zuul drops the following warnings:

  All regular expressions must conform to RE2 syntax, but an
  expression using the deprecated Perl-style syntax has been detected.
  Adjust the configuration to conform to RE2 syntax.

  The RE2 syntax error is: invalid perl operator: (?!

This patch replaces the 'irrelevant-files' to 'files' with explicitly
listing the pattern which files should be the tests run against.

(cherry picked from commit 9b77bae8a32ff41712b96bb6a67c7eacae45a4c9)
