The configuration preservation mechanism fails to keep items was are unset as unset. For busybox this causes issues when building with custom settings in the SDK. Therefore preserve busybox unset settings. In addition we preserve non-package selection unset settings because they may be important for making sure we compile and identical package for packages that are recompiled in the SDK. Now that SDK not longer ships .config this becomes relevant for any use of the SDK. Signed-off-by: Daniel Dickinson <lede@daniel.thecshore.com>
