base-files: add all buildinfo with INCLUDE_CONFIG

CONFIG_INCLUDE_CONFIG option is helpful for being able to rebuild the
exact same firmware as you see on a live OpenWRT instance, but it's
crucially missing feeds information, so we can't rebuild the exact same
package versions. This commit fixes this by adding the remaining feeds
(and version) buildinfo files to the image.
