adjust to wineasio 1.2 update

[zurgeg]

• Where can the part be found?
  Under the wineasio section, at least in the Arch build guide.
• What is wrong with it?
  At least in wineasio 1.2.0, make 32 outputs wineasio32.dll and wineasio32.dll.so. Ditto for make 64 (but with 64 instead of 32 obviously). The guide says to copy wineasio.dll and wineasio32.dll.so for both archs. This can be seen in the "building wineasio" section of this terminal recording I did
• What should it be instead?
  Just change wineasio.dll(.so) to wineasio(arch).dll(.so)
