libsensors: Adjust memory pre-allocation steps

Browse Source 
Make memory pre-allocation steps depend on the sensor type. Things like
voltages, temperatures or fans are typically plenty, however vid and
chassis intrusion are typically only a few, and there can only be one
beep_enable by design. This saves a small amount of temporary memory
for cheap.
