macvim: fix building with nix-daemon (#102975)
When building MacVim with nix-daemon it tries to place the derived data
into a path rooted in `/var/empty`, which fails. Specifying the derived
data path ourselves fixes this problem.

# against the system anyway so it doesn't really matter that the Vim binary will too. If we
# decide that matters, we can always patch it back to the Nix libsystem post-build.
# It also picks up libiconv, libunwind, and objc4 from Nix. These seem relatively harmless but
# let's strip them out too.

# Note: If we do add a post-build install_name_tool patch, we need to add the
