Subject: [PATCH] mpd: fix 0.23.8 on darwin

- 0.23.8 includes https://github.com/MusicPlayerDaemon/MPD/commit/c975d8b94316c86bf5950ed3abeba394e1263677
- said change fixes deprecation warnings introduced in the 12.0 sdk, using definitions from the 12.0 sdk
- nixpkgs uses 10.12 and 11.0, neither of which are the 12.0 sdk
- this will gracefully degrade into a no-op when that changes
