Handle statefs Battery.State = "low" correctly
Handle statefs Battery.State = "low" correctly

Initially Battery.State did not have a separate "low" state. Now that
it does, mce does not recognize it and falls back to assuming "unknown".

Add lookup table entry for low statefs battery state and map it to
mce internal low battery state.

[mce] Handle statefs Battery.State = "low" correctly. Fixes JB#27079
