[ostree] main: Add --link-checkout-speedup option to commit

    main: Add --link-checkout-speedup option to commit
    
    And disable devino scan by default.  For the gnome-ostree build case,
    our commits are from "make install DESTDIR=", so they won't be
    hardlinks into the repo.  In that case, particularly as the repository
    size grows, the cost of building up the devino -> checksum mapping
    becomes a problem.
    
    The compose step will use this option though.
