witherspoon: Remove `witherspoon` naming from fan watchdog

Remove the use of `witherspoon` in the names of the recipe, config
files, and services of the fan watchdog. This is in prep to use this
same fan watchdog on other machines within meta-ibm that have different
configurations.

Tested:
    Witherspoon image matches image prior to change
    Flash image to Witherspoon and force watchdog to trip
