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.
