Subject: defconfig: Add script

Simple script for initializing the configuration from an existing
configuration file (usually a minimal configuration).

Just copying the minimal configuration to .config would usually work,
due to Kconfig semantics, but having it be a full configuration file
from the start might be handier and less confusing.
