    ci: Collect coverage information from all tests
    
    Instead of doing a specific run to get testing coverage, collect the
    information of all tests being done. Since some of these will check for
    different build options, it's not possible to do that from a single run.
    
    This way we will get accurate information for all code that is being
    actually exercised by the tests.
    
    In consequence, using eatmydata to run the tests is no longer ok,
    since there is the possibility that it also eats the coverage reports
    that are generated during test runs.
