`lightnind` is missing CLI options on darwin

[plebhash]

I need to run clightning on my darwin setup. More specifically, I need to call lightningd --bitcoin-datadir=${bitcoin_dir}.

However, this CLI option is not available on the darwin build.

Steps To Reproduce

Steps to reproduce the behavior (on darwin):

$ lightningd --bitcoin-datadir=.
2024-04-18T13:47:28.658Z INFO    lightningd: v24.02.1
lightningd: --bitcoin-datadir=.: unknown option

I tested with installations both via:

• Nix
• Homebrew

Expected behavior

Here's the expected behavior (validated on linux):

$ lightningd --bitcoin-datadir=.
