s3 build: when detecting to use internal zlib, put "-I../lib/zlib" first in CFLAGS

This should fix a build error on our Tru64 build farm box where a zlib.h is
found in an include path handed in via external CFLAGS, but that zlib.h belongs
to an old zlib. So in ndr_compression.c, "#include <zlib.h>" includes the wrong
header for the internal zlib.
