util: Add miniconfig, a script to minimize coreboot configurations

This script produces a "minimal" configuration from a full coreboot
configuration, e.g. a configuration file that only contains the differences
between the default configuration of a board and the input configuration
file.

Usage: util/kconfig/miniconfig config.big config.mini

This will read config.big and produce config.mini. If you omit config.mini,
config.big will be changed in place.

Minimal configurations are easier to read and more robust when reusing
them among different versions of coreboot as they reflect exactly the
changes made to the default configuration instead of a full snapshot
of all configuration options.
