fcron: Update to 3.2.1

- Update fcron from 3.2.0 (Jul 2014) to 3.2.1 (Jun 2016 - latest version)
- Updated rootfile
- Changelog
	From version 3.2.0 to 3.2.1
	     * @-line can now be run every second (minimum every 10s previously)
	     * Fixed occasional 1s slippage. This was due to a race condition
	       between when time_to_sleep is run and when we compute how long to
	       sleep for, which could happen in the following second: if that
	       happened we end up sleeping for 1s instead of not sleeping at all.
	       The fix was to replace time_to_sleep() by next_wake_time().
	     * add From: header to emails. Similarly to other crons, use: "From:
	       %s (fcron)" with %s being either the user the job is run as or the
	       value of MAILFROM.
	     * The installation script now supports systemd fully.
