The leak in daemonize() is harmless, we're about to exit anyway. Fix
it still to make valgrind happy.
The leak in do_features() is real, as the function is called
periodically by the daemon, for all actions. If the intervals at set
low and the system has many sensors, the leak could be significant,
maybe 150 kB/day.
