[tracker/wip/carlosg/ci-pipelines: 6/7] ci: Run coverage on all test jobs

[Carlos Garnacho <carlosg src gnome org>]

commit 015faa8cd723b758a234e6af2d5596807243c842
Author: Carlos Garnacho <carlosg gnome org>

    ci: Run coverage on all test jobs
    
    And have the coverage job merge all results. So far this is mostly
    repeated work with maybe some slight timing-related variances in
    code paths, but this may be useful to get an unified coverage report
    for different compilation flags in the future.
