Update snprintf.m4, add _HW_FUNC_XPRINTF_REPLACE

- Add _HW_FUNC_XPRINTF_REPLACE again to snprintf.m4, in a modified way.
  Use AC_LIBOBJ([rrd_snprintf]) instead of original AC_LIBOBJ([snprintf])
- Fixes the following configure messages under MinGW-w64:
  ./configure: line 14694: _HW_FUNC_XPRINTF_REPLACE: command not found
  ./configure: line 14752: _HW_FUNC_XPRINTF_REPLACE: command not found
