xfce4-battery-plugin using high cpu

[Kevin Otte]

On a fresh install of Xubuntu 18.04, xfce4-battery-plugin is using is using most of a CPU, is currently the top memory consumer on the machine, and is driving the temperature up. Killing the process causes it to restart, and this behavior returns within a day or so.

This appears to be the same problem I encountered in #1683897 but that was in a non-LTS version and the problem was not addressed before it went unsupported.
