    Fix incorrect top-level directory for .ostree_repo_checksum

    This commit adjusts the subcloud destination for the
    .ostree_repo_checksum file during prestaging. The proper place for the
    checksum file is at the same level as the ostree_repo directory, not
    inside it.

    Test Plan

    PASS - Peform subcloud prestaging. Verify that the checksum file is
    transferred to /opt/platform-backup/.ostree_repo_checksum rather than
    /opt/platform-backup/ostree_repo/.ostree_repo_checksum.

    PASS - Install subcloud from prestaged data. Ensure the checksum
    is properly found and used, avoiding the ostree fsck.
