Summary: As per actions/runner-images#709 there started to be some issies with Ubuntu envs running out of space. This should fix it. Also our Cargo builds use a lot of space, changing them to be non-incremental and removing debug symbols keeps the build fast, but greatly reduces the disk space usage leaving us enough space on GitHub Actions virtual machines.
