[Bug-cpio] Patch to detect setlocale function

[Mitsuru Chinen]

Hi guys,

It seems that cpio-2.6 has a bug with detecting setlocale function.
In lib/system.h, though HAVE_SETLOCALE is checked, but
HAVE_SETLOCALE is not defined with configure script.
And `#ifdef HAVE_LOCALE_H' isn't necessary in src/main.c and src/mt.c
once lib/system.h works correctly.

I've created the patch for this issue. Could you check my patch?
