Add check for RHEL7/CentOS7 experimental userns disabled
...
Add a check in `check-config.sh` to see if we are running on a RHEL7 or
CentOS7 system, which may report that CONFIG_USERNS is OK/enabled, but
user namespaces still won't work because of the experimental feature
flag added by Redhat.
This will add a warning if it is actually disabled and notes what has to
be added to the grub/boot command line to enable it.

Enhance check-config.sh
...
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.
