Ensure both logger and syslogd output the same version string

Slight differences in output when called with `-v` flag:

  - Should output to stdout, that's what people expect (not an error)
  - Should output *project* name and version, for syslogd this is not
    so obvious since it *logs* 'syslogd vx.y.z' while the version is
    'sysklogd vx.y.z'
