Ignore deprecation warning for daemon on macOS

Ignore deprecation warning for daemon on macOS

macOS warns that we should posix_spawn instead. However posix_spawn
would require a major redesign of code to daemonise or drop the --daemon
feature on macOS. Ignore the clang warning in order to allow -Werror
compile on macOS.
