Stamp daemon log lines only outside the journal

The daemon makes the logger of each part in one place. Under the
journal, which sets JOURNAL_STREAM and adds its own time, the lines have
no time stamp. Otherwise every line has the standard time stamp, the
onechat lines too, so that no line has two time stamps and none has
none.

The start line names each value: the socket, the model and its effort,
the directory where the commands run, whether WhatsApp is linked, and
the number of active schedules.
