yosys: remove pointless patching

This fixes the patch introduced in:

94a047ca74cb (yosys: fix build on darwin, 2021-11-09)

Because we supply yosys with an external build of ABC, the patched
ABCMKARGS variable is without influence. Even if we were building with
in-tree ABC, that part of the patch is wrong, so drop it altogether.
