same-file patch when 'ls' doesn't default to POSIX locale

[Paul Eggert]

On second thought, that patch is so obviously needed that I installed
it on the trunk.  Here it is again.  Not sure whether it should be on
the b5.9x branch at this point.

        * tests/cp/same-file: Execute 'ls' in the C locale, so that it
        uses POSIX time stamp formats.  Problem reported by John Nixon in
        <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00062.html>.
