[oe] [meta-browser] New chromium warnings

[Gary Thomas]

I'm now seeing these warnings with the latest OE-core:
   WARNING: chromium: invalid PACKAGECONFIG: component-build
   WARNING: chromium: invalid PACKAGECONFIG: use-gl
   WARNING: chromium: invalid PACKAGECONFIG: ignore-lost-context

I looked at the recipes and those config strings are not mentioned
in the PACKAGECONFIG setup which is what is triggering the error.
