For ostree_repo_export_tree_to_archive(), and 'ostree export', when the exported tree contains multiple files with the same checksum, write an archive with hard links. Without this, importing a tree, then exporting it again breaks hardlinks. As an example of savings: this reduces the (compressed) size of the Fedora Flatpak Runtime image from 1345MiB to 712MiB. Resolves: #2925
