[package] add fancontroled

Add fancontroled (fancontrol for embedded devices) package. fancontroled
is linux daemon written in C implementing a temperature dependent fan
speed control. fancontroled provides similar functionalities like
fancontrol script from lm-sensors; but fancontroled does not need bash
or other dependencies (except lm-sensors library). That makes it
suitable for embedded devices.

fancontroled.init file contains parameters for D-Link DNS323 device.
