crypto: fix build when OCSP-stapling not provided

node_crypto.cc attempts to handle the case where OCSP stapling APIs
aren't provided by using NODE__HAVE_TLSEXT_STATUS_CB. But the build
would actually fail in this case because of a couple of places that were
missing #ifdefs.

With this change the build works although, as expected,
test-tls-ocsp-callback.js will fail.
