[ostree] Rename libarchive write API to "export", matching command line

[Colin Walters <walters src gnome org>]

commit b08b1abccdb6f8614750b31f2e3dc572e7b7bc8a
Author: Colin Walters <walters verbum org>

    Rename libarchive write API to "export", matching command line
    
    I was going to add new API for importing, and it was really confusing
    that what I think of now as import and export both had "write" in the
    name.  It's just clearer to talk about the direction.
    
    At the same time, include `Export` in the options structure.
    
    This isn't an ABI break as the API isn't in a release.
