main: Wait to daemonize to just before entering the main loop

To be able to get correct exit codes in case of error, we have to delay
the daemonization to just before entering the main loop. Otherwise the
init scripts might assume everything started fine and go ahead when that
was not the case.

The initialization error messages are printed to syslog instead of
stderr, which would need a rework in the future of either the logging
functions, or the call sites to distinguish what belongs where. But at
least for now we get correct exit values.
