Install witherspoon-reset-fan-watchdog service

This is a witherspoon only service that will
reset the fan watchdog circuit on a poweron, which
would bring the fans out of watchdog control if they
previously were.

The watchdog is reset by toggling a GPIO that feeds
a latch that drives the watchdog signal to the fan
controller.  The GPIO parameters are obtained from
an environment file.

The witherspoon-fan-watchdog.bb recipe will have other
watchdog related services added to it in the future.

Resolves openbmc/openbmc#1687
