hooks/pre-auto-gc-battery: allow gc to run on non-laptops

Desktops and servers tend to have no power sensor, thus on_ac_power returns
255 ("unknown").  Thus, let's take any answer other than 1 ("battery") as
no contraindication to run gc.

If that tool returns "unknown", there's no point in querying other sources
as it already queried them, and is smarter than us (can handle multiple
adapters).
