Revert "src: exclude node_root_certs when use-def-ca-store"

This reverts commit be98f26.

The above commit prevented the functionality of --use-bundled-ca if
Node has been built using --openssl-use-def-ca-store, since there will
be no bundled ca included and no way to use them.

I only noticed this when trying to add // Flags: --use-bundled-ca to
test-tls-ccnic-whitelist.js to force it to use the bundled ca and allow
the test to pass.
