kbuild: doc: remove outdated description of the limitation on -I usage

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

Commit cdd750bfb1 ("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)

Note that in the assignment there is no space between -I and
the path. This is a limitation of kbuild: there must be no
space present.
