Monitor fan apps for watchdog protection
This overrides the fan-control and fan-monitor service files
to call the fan-watchdog-monitor service on fails.
The watchdog monitor service will start the obmc-fan-watchdog-takeover
target to expire the fan watchdog when these apps have exceeded
their retry limits.
Note that fan-presence-tach and fan-control-init do not need watchdog
protection because they are in the poweron path and will fail the
poweron if they fail.
Resolves openbmc/openbmc#1688
