Subject: libxtables: compiler warning fixes for NO_SHARED_LIBS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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
