deploy cleanup not removing all unmodified files

The linting patch If87fceb79e384e26f021a9c85a2e9d7413ce421e
broke the cleanup script so unmodified maven-metadata.xml files
were not properly being cleaned up before upload to Nexus. This
caused the maven-merge job to update maven-metadata.xml files
outside of what was actually modified. So when 2 maven-merge jobs
running on different streams are run at the same time they would
overwrite each other with old data.
