[PATCH] Swap including order of util.h and string.h of util/string.c

[Hitoshi Mitake]

Current util/string.c includes headers in this order: string.h, util.h
But this causes build error because __USE_GNU definition
is needed for strndup() definition like this,
% make -j
touch .perf.dev.null
    CC util/string.o
cc1: warnings being treated as errors
util/string.c: In function â??argv_splitâ??:
util/string.c:171: error: implicit declaration of function â??strndupâ??
util/string.c:171: error: incompatible implicit declaration of built-in function â??strndupâ??

So this patch swaps order of including headers.
util.h defines _GNU_SOURCE, and /usr/include/features.h defines __USE_GNU as 1
if _GNU_SOURCE is defined.
