tests: omit covered files (#10801)
tests: omit covered files (#10801)

When the tests complete, we get a lovely list of files that are 100%
covered by tess - woohoo!

As the file count grows, seeing anything that isn't 100% covered is
harder, so we can omit any file that coverage.py reports is fully
covered.
