Subject: [PATCH] ci: Enable coverage reports in test build

While we don't have an high number of tests, we still have some code
coverage and so we can track this via gitlab CI, given that it supports it
natively.

So add gcovr to the DockerFile dependency, build with -Db_coverage=true
meson native parameter, and add another manual job to make ninja to generate
the coverage reports on requests or in any master or tag ref.

Keep the artifacts around to be able to browse the generated HTML files and
eventually print the text reports so that they can be parsed by gitlab.
