Fixup code coverage, add to CI

[evelikov]

This PR starts off with a trivial annoyance fix the last day or so - removing the tests, use Ubuntu 24 for CodeQL.

Then an earlier commit of mine is reverted which broke the code coverage and finally a CI action is added. For the last piece a CodeCov account is needed + trivial setup for the CODECOV_TOKEN.

Edit: here is an illustrative link to the CodeCov web UI https://app.codecov.io/github/evelikov/kmod

Thanks for integrating Codecov - We've got you covered :open_umbrella:

@stoeckmann the first commit means we don't get any more CodeQL complains in the tests, as seen in your earlier PR.

@lucasdemarchi not 100% if you already have CodeCov account or the above welcome message is because of mine. I suspect the latter isn't enough - the token is created against my fork and not the upstream repo.

If we find the PR notifications to be too much (say thee threshold is too low so new PRs are repeatedly flagged as low coverage), we can tweak them via the codecov.yml file.

As indicated the Ubuntu 22.04 is still semi-borked and I'm somewhat tempted to remove it. All other distros have one version/variant and the newer Ubuntu 24.04 seems stable - famous last words...

[lucasdemarchi]

Added the same commit as in #229 here. Let's see if it passes now.

I think you meant #235 and yes it does. Thanks a bunch

[lucasdemarchi]

Applied, thanks
