   warning: failed to remove CMakeFiles/Makefile.cmake

Found the job that saved the directories with root permissions
https://gitlab.com/tarantool/tarantool/-/jobs/577768553

The issue appeared because the issue caused job used the script
runner to run docker in it as additional command. It caused the
the gitlab-runner default workspace cleanup to be outside the
docker (in opposite to the jobs when docker runner used, the
cleanup runs inside the docker and no fails exists ever).
Cleanup failed to remove files created by root inside the docker
container before and which were shared to global host.

To fix the issue need to run docker images using the gitlab-runner
only in RO mode with Out-Of-Source builds in it. Either use the
docker runners when docker containers are needed. Anyway script
runner jobs with additional calls to dockers can't be control for
the branches of developers, to avoid of it need to make local
cleanup instead of default to the working paths for each job with
script runners use.

Decided to setup gitlab-runner configuration as described in:
https://docs.gitlab.com/ce/ci/yaml/README.html#git-clean-flags

Closes #5036
