[gvfs/standard-file-info] daemonfile: Set the standard::file attribute

    daemonfile: Set the standard::file attribute
    
    When requested, set the standard::file attribute.
    This attribute is going to be used by the GTK file
    chooser.
    
    GLib defines a name for this attribute, but we use
    the literal string here to avoid a hard dependency
    on a recent version of GLib, just for a macro.
