Battery: fix time calculations on some Linux systems
The calculations are based on the assumption that current_now (or power_now) are always positive. However, power_supply documentation in the kernel sources say nothing about it, and so some drivers provide a signed value (e.g. bq27xxx_battery_current). Discovered and fixed on ac100/paz00 netbook.
