PATCH 1/1 utils/genrandconfig: Add level 2 optimization option

Currently all random defconfigs which are used in autobuilder use size optimizaion(-Os).
Adding "-O2" optimization will give better test coverage. In many cases software gets built with speed optimization rather than size optimization. So let's add Level 2 optimizaion option to be genertated in random defconfigs, so we could be able to test how packages are built with "-O2" in autobuilder.
