[Buildroot] [PATCH 1/1] package/unifdef: add new package

[Thomas Devoogdt]

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.

See: https://github.com/WebKit/WebKit/commit/f76a7e30e5749af897b83cc75b2534b1afa32552
