wspoon: Revert fan watchdog timeout

An increase to the fan watchdog timeout was done to mediate a BMC
performmance issue, which has now been resolved, so reducing the fan
watchdog timeout. The timeout should be set to 5 seconds (instead of
originally 3 seconds) to functionally align with the 5 second timer that
fan control uses in adjusting fan speeds.

The fan watchdog timeout increase was done under:
    https://gerrit.openbmc-project.xyz/#/c/8398/

The performance issue with the OCC patches:

    (Series = Locking fixes for FSI, SBEFIFO, OCC)

Tested:
    The fan-watchdog.conf file in BMC image contains 5 second timeout
