python3Packages.minify-html: fix build on darwin

maturin >= 1.13.0 doesn't add `-undefined dynamic_lookup` because
it finds the flags in minify-html-python/.cargo/config, but cargo
doesn't look there so neither system adds the flags.

see https://github.com/NixOS/nixpkgs/issues/541257 for more info
