dpctl: Fix broken Windows build due to missing strndup.

AppVeyor reports:

  lib/dpctl.c(1433): error C4013: 'strndup' undefined;
                                  assuming extern returning int
  make[2]: *** [lib/dpctl.lo] Error 1

Replacing missing 'strndup' with a portable pair of functions.

Fixes: bf8812cd7e20 ("dpctl: Add add/mod/del-flows command.")
