gen_pimrules: Update the Boot Progress Sensor

The boot progress sensor has moved from the
/org/openbmc/sensors path to /xyz/openbmc_project/state/host0.
(Reference: the phosphor-ipmi-sensor-inventory%/config.yaml files
under the openbmc/openbmc repository).

Update gen_pimrules with the correct sensor path and value.

Tested: Verified Witherspoon powered on to the Host OS.
