sys-apps/lm_sensors: Version bump to snapshot release from 2016-07-25; Package now uses module-load service

Changes:
========
 - Based on latest unreleased changes (snapshot release from 2016-07-25;
   updated/added detection for Fintek F81768, Nuvoton NCT6793D, Microchip
   MCP9808 and Mark F71868A chips; various fixes for sensors-detect, see
   https://git.io/v6Wig for all changes)

 - sensors-detect now writes to "/etc/modules-load.d/lm_sensors.conf" and
   uses a config file protection mechanism like known from emerge (i.e.
   after making changes you have to call tools such as dispatch-conf,
   cfg-update or etc-update to merge the changes;
   new "--no-gentoo-config-protect" parameter will disable config file
   protection)

 - Due to previous change lm_service service no longer loads modules. You
   have to use mechanism your init system provides to do that (i.e. make
   sure your init system's modules-load service is enabled).

 - Ebuild is now multilib compatible (see bug 529684)

 - Runscripts no longer passes config file as argument. While this removes
   the possibility to use different configurations per default services it
   allows you to use "/etc/sensors.d" (see bug 490502 and bug 307249)

 - Runscripts improved in general. I.e. if you start fancontrol service
   without a valid config (so that fancontrol doesn't start and exit with
   an error) you will now know at least, that the service didn't start.
   Now you will also have reliable status functions to know service state.
