test: adapt testing to RHEL 9.4

- Disable downloading of build cache.
- Disable uploading of results to cache.
- Add build tags to exclude the btrfs graphdriver for the container
  dependencies.
- Remove awscli2 and btrfs-progs-devel from the install dependencies
  script (not available on RHEL).
- Remove the check-build-coverage step in gitlab-ci.  It requires
  reading the build cache.
