In the preceding commit we have adjusted test slicing to be one-based
when using the "ci/run-test-slice.sh" script. But we also have an
equivalent script for Meson that is still zero-based, which is of course
inconsistent.
Adapt the script to be one-based, as well, and adapt the GitHub workflow
accordingly. Note that GitLab doesn't yet use the script, so it does not
need to be adapted. This will change in the next commit though.
