autoconf: don't assume sys/stat.h and sys/types.h when testing C89

Browse Source 
Problem reported by Patrick Pelissier in
<http://lists.gnu.org/archive/html/bug-autoconf/2010-11/msg00019.html>.
* lib/autoconf/c.m4 (_AC_PROG_CC_C89): Don't include sys/types.h
and sys/stat.h.  Instead, define a dummy struct stat.  C89 doesn't
guarantee sys/types.h and sys/stat.h.
