vendor.xilinx_spartan_3_6: reconsider bitgen defaults.

Browse source 
Previously changed in 27063a3b.

I haven't realized the .bin file is the same as the .bit file without
a small header. That means generating it is free and it's just easier
to let programming tools to be able to always rely on its existence.
