Remove asterisks from phpcpd command line.

[alxp]

What does this Pull Request do?

Somehow even though it ran correctly in my local Linux box with the "--suffix *.php" etc options, it was still failing in CI.

Removed the asterisks and tested on the branch 'GitHub-actions-test-breakout-mirador' of islandora_ci.
