// SdNotify sends a message to the init daemon. It is common to ignore the error.
// If `unsetEnvironment` is true, the environment variable `NOTIFY_SOCKET`
// will be unconditionally unset.
//
// It returns one of the following:
// (false, nil) - notification not supported (i.e. NOTIFY_SOCKET is unset)
// (false, err) - notification supported, but failure happened (e.g. error connecting to NOTIFY_SOCKET or while sending data)
// (true, nil) - notification supported, data has been sent
