Consider a discharging UPS as "on battery"

Browse source 
Implement get_{on,low}_battery() methods on HID devices for Linux. This will
treat discharging UPSes like batteries and set the "on-battery" and
"on-low-battery" properties accordingly.

This also fixes the test_ups_ac() case in the Linux integration tests.
