During stage 3 of compilation, Zig calls `std.zig.system.darwin.macos.detect`,
which parses /System/Library/CoreServices/.SystemVersionPlatform.plist and
/System/Library/CoreServices/SystemVersion.plist[^1] to determine the OS
version. These paths are inaccessible when the sandbox is enabled, which causes
the build to fail with `OSVersionDetectionFail`[^2]. Fix the build with the
relaxed sandbox option by adding these paths to `__impureHostDeps`.
