Allow to run in daemon mode without log file.

It's kind of silly to insist in having a log file in daemon mode.

This commit removes the dependency of --daemon on --logfile and makes
/dev/null the default log file. Consequently, running dss --daemon
--run without specifying --logfile no longer fails, and nothing will
be logged by default.

The documentation is updated accordingly.
