ipset: Don't include host headers

Add a patch removing /usr/local/include from the include path.

Fixes:
http://autobuild.buildroot.net/results/4f5/4f55c2415281c6204500efe28fe9e24c8ef73863/

Technically speaking this autobuild failure has already been fixes when
-Werror was removed in commit a923b44112 (ipset: add patch to fix
--enable-debug build). But the warning in this case indicates a real problem
that needs to be fixed by itself.
