upower: Add a -b/--battery option to dump only battery information

Browse source 
This is useful when asking people to give information about battery
health. It avoids having to give two-step instructions of first
enumerating devices with `upower -e`, then looking for a device whose
name starts with `/org/freedesktop/UPower/devices/battery_`, then
running `upower -i` on that device.
