systemd-python: add systemd.daemon wrapping sd-daemon
Please see the documentation (e.g. pydoc3 systemd.daemon) for full description. As usual, systemd._daemon wraps the raw interface, while systemd.daemon provides the more pythonic API. sd_listen_fds, sd_booted, sd_is_fifo, sd_is_socket, sd_is_socket_unix, sd_is_socket_inet, sd_is_mq, and SD_LISTEN_FDS_START are currently wrapped.
