  d.barscale: Correct the length option description (#8069)

The label said the length is in map units, but draw_scale() reads it in the
units given by the units option and only falls back to map units when that is
not set, so length=5000 units=kilometers draws a 5000 km bar. Say so, and note
that the default of 0 picks a length automatically.
