Subject: kconfig: add defconfig_list/module option
This makes it possible to change two options which were hardcoded sofar.
1. Any symbol can now take the role of CONFIG_MODULES
2. The more useful option is to change the list of default file names,
which kconfig uses to load the base configuration if .config isn't
available.
