[ostree] core: Remove dead code from OstreeRepoFile

[Colin Walters <walters src gnome org>]

commit 14d682305b9c8d65e46f0aaf31e6851cf2042193

    core: Remove dead code from OstreeRepoFile
    
    Originally I thought it would make sense for OstreeRepoFile to be
    mutable, and it probably does, but we should do it in a different way.
