BIND 9.17 changed exit code of skipped test to meet Automake expectations infa505bfb0e. BIND 9.16 was not rewritten to Automake, but for consistency reasons, the same SKIPPED_TEST_EXIT_CODE preprocessor macro is used (though the actual exit code differs from the one in BIND 9.17). (cherry picked from commitfa505bfb0e)
