[gnugo-devel] remove unused code

[Arend Bayer]

The size of make_dragons() is keeping to irritate me. Here is an obvious
place to save 40 lines -- the code to compute the dragon genus was
outsourced to compute_dragon_genus() by paul_5_4.1 more than a year ago,
while keeping the old code, disabled. I think this can be removed
now.
