[Buildroot] [git commit] package/unifdef: add new package

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=7dbe844bae38aba8e6080da3b650b89f702c0f1c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

A small package that does "Selectively remove C preprocessor conditionals".

The package will be needed for the upcoming webkitgtk 2.40.0 release.
I personally added it to get started with 2.39.2.
