[Buildroot] [PATCH] utils/genrandconfig: Add level 2 optimization option

[Evgeniy Didin]

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.
