[PATCH 3/3] battery: add CURRENT_NOW

CURRENT_AVG is actually CURRENT_NOW (the EC code directly passes through
the value from the gas gauge instead of the internally used average).
We retain CURRENT_AVG as an alias for compatibility reasons, it will be
removed later.

This change allows an unpatched UPower (0.9.2) to calculate TimeToEmpty
and TimeToFull.
