Use default priority for sensor service

The sensor manager service is used by the host to read certain
sensors (PowerSupplyRedundancy, PowerSupplyDerating). The end goal
is to move these to their own DBUS services (or into phosphor-settingsd)
but until that is done, this service needs to get the default priority
that all other services get.
