sesutil: Add extra information specific to some SES devices to sesutil map

Rework stat2ascii preparing a buffer of what could be printed. This prevent the
risk of overflowing a static buffer.

Do not print those informations anymore in the "status" but into a new
"extra status" only printed if there are actually extra things to print.

Now add those extra informations:

* Thermal sensor temperature
* Cooling devices speed
* Voltage sensors, current consumption
