[gvfs/gnome-3-22] google: Fix reported file size

    google: Fix reported file size
    
    Ligdata recently added API to obtain a real file size. Use
    gdata_documents_entry_get_file_size if libgdata 0.17.7 is available
    instead of gdata_documents_entry_get_quota_used, which returns 0
    in some cases (e.g. shared files).
