Some 80's GM cars did this also.  I'm not sure why but I'd suspect having the 
+ wire run from the light to the underhood relay and fuse ( shorter distance 
) offers less chances of having a + wire rub through/  If the ground wire 
rubbed through, the lights would just stay on.

There might also be a chance a ground point near the headlight was difficult 
to locate.  Rather than running 2 wires some distance from the light, the 
circuit was reversed.  Less wiring, less weight, smaller package and lower cost.
