kbuild: doc: remove outdated description of the limitation on -I usage



Kbuild used to manipulate header search paths, enforcing the odd
limitation of "no space after -I".

Commit cdd750bf ("kbuild: remove 'addtree' and 'flags' magic for
header search paths") stopped doing that. This limitation no longer
exists. Instead, you need to accurately specify the header search path.
(In this case, $(src)/include)
