meson: Fix psusensor

The psu sensor's process name was incorrectly set to psutempsensor and
is inconsistent with the service unit.
Fix this and use `psu` as the configure option instead of `psu-temp`,
because it is really psusensor including temperature/current/voltage/fan
sensors.

Tested: Verify the build binary is named as `psusensor`.
