github ci space cleanup

[spoore1]

In newer versions of Fedora, the github runners are filling disk space
during testing. This is to try to alleviate some of the space
restraints so that the tests can complete.

Do we already know what is eating the disk space? Perhaps we don't clear something in /tmp?

I was not aware of this issue but https://github.com/SSSD/sssd/actions/runs/19629329150/job/56266099369?pr=8212 is a run on fedora-43 which fails with tee: /home/runner/work/sssd/sssd/pytest.log: No space left on device about 1/3rd of the way through.

The same PR run on fedora-42 completes successfully: https://github.com/SSSD/sssd/actions/runs/19629329150/job/56266099393?pr=8212

@spoore1 I don't think this is strictly related to tests or framework. It may be some process misbehaving in Fedora, since it started happening only recently and only on 43 and 44, with this, I think we may eliminate issue in SSSD. Try to take disc usage while the test runs, something like (Gemini helped; modify the pytest command to be the same as for PR CI):

( while true; do echo -e "\n--- DISK USAGE REPORT ($(date +%H:%M:%S)) ---"; df -h | head -n 2; sleep 5; done ) & MONITOR_PID=$!; pytest --mh-config=./mhc.yaml -vvv -k test_access_filter__single_ldap_attribute_permits_user_login --mh-topology=ldap; kill $MONITOR_PID

Dropping this PR since we resolved the issues elsewhere.
