[OE-core] [PATCH] matchbox-panel: silence some pointless warnings

[Ross Burton]

The battery applet emits a warning if the hardware doesn't have a battery (it
shouldn't) and the parser emits a warning if two separators are used in a row
(which happens if the hardware has a keyboard).  Silence these with a patch from
upstream.
