sesman: don't spit on the console when starting

As the Debian patch[1] expresses, spitting messages on the console when
a process starts in background is a bad idea. Everything should be
written to log file and daemon should start silently. This is a first
step to shut up daemons.

Got some idea from Debian Remote Maintainers and Thorsten Glaser,
thanks!
