traced_probes: Implement BatteryCounters for CrOS and Linux

CrOS and Linux doesn't have the Android hwbinder for getting battery
counters. Implement data source "linux.sysfs_power" that reads the
counters from sysfs (e.g. /sys/class/power_supply/BAT0) entries:

* capacity: battery capacity in percentage.
* charge_now: the current coloumb counter value in uAh.
* current_now: the current in uA.
* current_avg: the smoothed (average over a period) current in uA.
