DUT repair should try re-installing software if AC power isn't detected

Reported by jrbarnette@chromium.org, Jun 10 2016

Issue description

The Autotest repair process restricts the specific procedures
it tries based on the failure symptoms.  In particular, if a
DUT says "I can't run tests because I'm not plugged in to AC
power", the only repair procedure we try is to turn power on
using RPM.  In particular, we don't try to reinstall the
stable repair image.

ITOT bugs where the DUT has AC power but can't detect it are
a thing, and they're likely enough that they've occurred in
the wild (see  bug 617704 ).  So, when the symptom is "AC power
is not plugged in", repair needs to try re-installing stable
software.

[autotest] In repair, if no power, try reinstalling the software.

It's possible for a DUT to have AC power, yet have a software bug
that causes it to report "no AC power."  So, make "no AC power" a
trigger for all repair actions that reinstall the software.
