libxtables: compiler warning fixes for NO_SHARED_LIBS
Fixes two issues with NO_SHARED_LIBS: - #include <dlfcn.h> is ifdef'ed out and thus dlclose() triggers an undeclared function compiler warning - dlreg_add() is unused and thus triggers an unused function warning Test: builds without warnings Signed-off-by: Maciej ┼╗enczykowski <maze@google.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
