diff: don't use locales after local-specific sorting fails

* src/dir.c (compare_names): Don't invoke strcasecmp if
locale-specific sorting fails, because POSIX.1-2008 says strcasecmp
has unspecified behavior outside the POSIX locale.  See:
http://lists.gnu.org/archive/html/bug-diffutils/2011-05/msg00008.html
