phpunit: Exclude /languages/messages from coverage report

Indexing these files takes about 5-10% of the run time when generating
code coverage reports for core. It has no coverage at the moment and
probably won't any time soon given it's just variable declarations.

At least for now, exclude it to significantly speed up generating of
coverage reports.
