power_ProbeDriver: refactor to use SysStat

This test pre-dates the SysStat object being created which unifies
power supply query & checking.  Refactor the test to use it.

Note, the refactor removes the notion of CrOS devices having multiple
batteries that should be checked.  May need to revisit this if
detachables have batteries in both lid & base and both are presented
to sysfs.

power_ProbeDriver.probe_ac: Allow battery discharge in some cases.

Some devices allow for battery discharge on AC.  In particular those
which carry the following chrome-ec CONFIG option,
CONFIG_CHARGER_DISCHARGE_ON_AC.

While we could generate a whitelist via,
  git grep CONFIG_CHARGER_DISCHARGE_ON_AC board/*/board.h
  board/reef/board.h:#define CONFIG_CHARGER_DISCHARGE_ON_AC
  ...

That would be difficult to maintain.  This CL proposes an alternative
which is to survey that:
  1. AC is in fact charging
  2. state-of-charge is> 95%

which should demonstrate that charging has in fact been successful we
just so happen to be in the discharge phase of battery maintenance.
