[OE-core] [PATCH] bitbake.conf: Use -Og in DEBUG_OPTIMIZATION

[Khem Raj]

-Og is for optimized debugging experience.
this makes this consistent across different compilers especially gcc and
clang, -O in clang is equal to -O2 where as in gcc its similar to -O1
so it was not giving consistent debugging experience across compilers
