package/libnss: Re-add ZLIB_INCLUDE_DIR varible

Browse Source 
The libnss patch adding ZLIB_INCLUDE_DIR is added to upstream on
2020-01-07 but the 3.49.1 release on 2020-01-13 does not contain this
patch, so we have actually prematurely removed it from Buildroot.

This only affects host-libnss when libzlib is not installed in the host
system. When building for the target, the toolchain-wrapper already
looks in the target sysroot default include path - where zlib.h is
installed.

Re-add this patch, so that we can build host-libnss 3.49.1.

Add ZLIB_INCLUDE_DIR variable
On Linux platform[1], the build system forces to use zlib from the
system instead of compiling the one located intree.
The following error is raised when the zlib header is installed
somewhere else than in the default system include path:
ssl3con.c:39:18: fatal error: zlib.h: No such file or directory
#include "zlib.h"
The same trick setup for sqlite include directory is reproduced for
zlib. The build system disallows in any manner to give arguments to the
compiler explicity.
The variable ZLIB_INCLUDE_DIR point to the directory where the zlib
header is located.
