[macOS Apple Silicon] Add support for -undefined dynamic_lookup

[nsabovic]

When compiling napi-rs (Node.js addons in Rust) the Rust compilation fails with

note: mold: fatal: unknown command line option: -undefined

The relevant flags are "-fuse-ld=/opt/homebrew/bin/ld64.mold" "-Wl" "-undefined" "dynamic_lookup".

I also encountered that, and seems like Mold has not been supported -undefined dynamic_lookup in their codebase. Hopefully it can be fixed so I can fully adopt mold in my projects ;)
