dir_import: Accept JSON data after the last object

This should really have been accepted from the start. Adding extra
elements to the top-level array might be useful for aux. data related to
the scanned files, e.g. map of seen uid/gids to names, information about
the scanned dev ids, etc. But since ncdu would throw an error on further
array elements, adding such information can't be done without breaking
compat with older versions. :(
