blender: un-break darwin

currently builds on aarch64-darwin, but not on x86_64-darwin.

Blender (specifically the ghost window library) depends on "metal" on
apple devices.
(For details see source/intern/ghost/intern/GHOST_System.cc line 416ff)

It cannot build without it. Metal support should be
introduced by apple sdk 11_1 (?) onward. Once this has been updated in
nixpkgs, this derivation can be revised.
