abuild: Build saved config files

Update abuild to allow for building saved miniconfig files.

If one or more config files exist for a platform under
    coreboot/configs, they will be built instead of the automatically
    generated default config.

The config filename needs to start with "config.$VENDOR_$BOARD" to be
    picked up by the abuild script.

- Update to version 0.10.0
    - Add -d parameter to specify the saved config file directory
    - Break 2nd half of create_config function into update_config
    to set the payload for saved config files.
    - Unset new payload Kconfig options that could be set in a saved
    config file.
    - Update a bunch of MAINBOARD variable names to BUILD_NAME since
    the build name isn't necessarily the same as the mainboard name.
    - Split build_target into two functions - build_target and
    build_config because one mainboard can now build multiple
    configurations.
    - Update remove target and call it directly from build_target()
    instead of from build_targets()
