wspoon: Make cooling-type service a oneshot

Change the type of the phosphor-cooling-type service to
a oneshot, and also tell it to remain after exit.

This is so that any services that depend on this won't start
until the the phosphor-cooling-type application is done so
they can rely on the cooling type property being set in the
inventory.

Tested: Checked that a service that depends on this one
        and gets the cooling type will read the correct value.
