hosted: consolidate sysfs-based battery measurement code

Several hosted targets read their battery state from a fixed
sysfs path. Get rid of the duplicated code by handling this
common case in power-linux.c.

Some targets use non-standard units in sysfs instead of the
typical microvolts / microamps, so allow the scale factors
to be overridden by the target.
