Enhance check-config.sh

Browse source 
Currently check-config.sh just said enable or missing, when I used
a fresh kernel, made check-config.sh happy, still can't start
container. It take me days debuging kernel and Docker and finally
found it's because I enabled some CONFIGs as modules and never
loaded these modules.

So I think it's necessary to let check-config.sh told users which
configs are enabled as modules.
