packaging: Make kernel config accessible to guest

Browse Source 
Provide the `/proc/config.gz` file in guest kernels that allow the guest
to determine the kernel configuration used to build the running kernel.

Note that since `gunzip` expects to rename the gzip'ed file it operates
on, to use this feature you need to run something like the following in
the container environment:

 ```bash
 # cat /proc/config.gz|gunzip -c
 ```

Fixes: #3445.
