[Biturbos4] After-run thermoswitch modification

[Rocket Science Racing]

The original article presented data showing only a 5 degree improvement in
the measured temperatures 15 minutes after shutdown. This is the proverbial
fart in a windstorm from an engineering perspective and neither worth the
effort nor the extra wear on the battery. It's a "feel good" mod.
