ci: confine docker and macOS jobs to main repository

Some of our CI jobs use project-specific GitLab runners (e.g. requiring the dind tag). The jobs then fail when someone forks the repository and opens a merge request. This commit confines those jobs to the knot/knot-resolver repository.

Oh, pytests needs lxc which is on group runners only, so it also does not work for forked repos. I'll add that as well.

Compare with previous version

Tested on my forked repository, seems to be doing what I want it to do.

IIRC in pytests case it can run unmodified on anything, but Tomáš set it to LXC as in this case it improved reliability of the tests due to the runners never doing multiple jobs in parallel on the same machine. Even so, this simple MR seems best to me.
