Fix sensord service install (#12376)

Why I did it
#4021 describes an issue that is still being observed on master image whereby sensord does not start in pmon due to missing service.

How I did it
Updated the lm-sensors install patch with a case for systemd

How to verify it
Verified that sensord is up in pmon after boot
