Supply missing axis labels for gnuplot toolkit (bug #51759).

* __gnuplot_draw_axes__.m (do_tics_1): Assign empty string to 'labels' if
  'labels' is empty (i.e., size 0x0).  Use repmat() to repeat labels when the
  number of labels is shorter than number of tics.  Remove the conditional test
  that resets index k to the start of labels when there are too few.
