cmake: settings: Don't add ext nffs include dir to global includes

The settings subsystem has been adding nffs's include dir to the
global set of paths. Presumably because app's will need acces. But
this is no longer necessary as we default to linking 'app' with FS,
which again has the NFFS include paths.
