linux: Add NoPollBatteries configuration option
For system integrators. If your firmware is helpful to user space
and automatically sends out uevent when the battery level changes
(rather than just the battery state) as on most machines,
you can enable "NoPollBatteries" in the configuration option,
and reduce power consumption from UPower and its listeners.
