test: add --use-bundled-ca to tls-cnnic-whitelist

If configued with --openssl-use-def-ca-store --shared-openssl the
following error might be thrown:

assert.js:86
  throw new assert.AssertionError({
  ^
AssertionError: 'UNABLE_TO_VERIFY_LEAF_SIGNATURE' === 'CERT_REVOKED'
    at TLSSocket.client.on.common.mustCall
(/Users/danielbevenius/work/nodejs/node/test/parallel/test-tls-cnnic-whitelist.js:71:14)
    at TLSSocket.<anonymous>

    at emitOne (events.js:115:13)

    at _combinedTickCallback (internal/process/next_tick.js:80:11)
    at process._tickCallback (internal/process/next_tick.js:104:9)

In this case the CA's used will be the ones shipped with OpenSSL. For
tests though we should be able to specify --use-bundled-ca as a fix for
the above error, but this functionality was broken by me in commit
be98f26
("src: exclude node_root_certs when use-def-ca-store").

That commit removed the abilty to use --use-bundled-ca if the build was
configured --openssl-use-def-ca-store.
