rustfmt: fix on darwin

Browse Source 
Reading this [rust-issue] it seems that we have to link against
rustc_driver. The [clippy.nix] expression already does something similar

Of the 4 executables found in the result of building rustfmt only
rustfmt and git-rustfmt needed to be linked. The other worked without
linking to rustc_driver.

[clippy.nix]: c8cf570dae/pkgs/development/compilers/rust/clippy.nix (L27-L36)
